The news team of the Open Minded Thinker Show is actually not a fan of the CNN monologue reporter, but his latest monologue about the obvious destabilizing policies of the Biden administration in Gaza has given us a sense of the overwhelming pressure of evidence that made CNN, for the first time, allow a brutal, truthful, anti-BB Netanyahu rant on its platform. This latest truth-to-power moment convinced us to add even further context to the omission made in the presentation by Fareed. Our commitment is to deliver factual news and impartial geopolitical analysis. We encourage you to engage with our content by liking and sharing this video to stay informed. Subscribe to receive timely updates on developments related to Palestine. You see, Fareed is the darling of the Democratic Party and the establishment. He sees Biden as an astute politician and great man who was able, within some few months in the White House, to douse the effect of Donald Trump's wavelength. The CNN monospace has made videos praising the ingenuity of the Democratic administration and specifically Biden. On some occasions, his takes are spot-on, while on many occasions, he has taken extreme favorable sides to promote the current government in power. He attempted this in the latest video, which has been latched upon by critics including us, to mock his distorted position about the conflict in Gaza. While using very strong words such as immorality to describe the failure of Biden's Israeli policies, he went at length to defend his friend Biden. He used two minutes of the video to explain how the Biden administration urged Israel to stop this and stop that, how the president himself tried to reign over Netanyahu for a cessation of hostilities and that and that. Yet he cleverly omitted the crux of the issue at stake. For us, he was trying to bury the mountain of blame which American policies over the years have generated on the state of affairs in Palestine. Fareed was trying to play on our intelligence, wherein he tried to cast the president as the good guy, while Netanyahu's government as the bad guys, and blatantly ignored, stating that the U.S. has supplied the Middle Eastern colonizers with the weapons that it has thus far used to prosecute the brutal war in Gaza. According to unverified estimates, most of the bunker-busting munitions used in Gaza to bring down towers and high-rise buildings were supplied by the American government themselves. Fareed even refused to acknowledge that Biden mirrored Netanyahu's policy of non-compliance and compromise when his government decided to bomb Yemen instead of genuinely pushing for a ceasefire and allowance of aid to the starving people of Gaza, as demanded by the Yemeni armed forces. The reality is that he tried but failed to convince us that Biden is a saint. Yet Fareed doubled down. Here's my tip. When Hamas launched its gruesome terror attack on Israel on October 7th of last year, President Biden made a decision based on conviction and calculation. He announced his complete solidarity with the country. Biden must have calculated that the only way to have any influence on Israel would be to hug it close, show real empathy, send it the arms it needed, and thus earn Israel's trust to shape its response. It was a thought-through strategy, but it has failed almost completely. From the start, the administration urged the Israelis to consider proportionality in their response to Hamas. Israel heard it and went ahead with one of the most extensive bombing campaigns in this century against a population of about 2.2 million people that by Israel's own estimates contained about 30,000 Hamas militants. By one January estimate, more than half of buildings across Gaza had been damaged or destroyed. The administration counseled Israel against a large ground invasion of Gaza, advising it to take a narrower, targeted approach aimed at eliminating Hamas militants and infrastructure. The Israeli government had lots of long meetings with U.S. officials and then again went ahead with the ground invasion. The Biden team urged a humanitarian pause, but only got a brief one when it was able to get the government of Qatar to broker a hostage exchange. After initial operations wound up, American officials told Israeli officials that what was done in the north of Gaza could not be done to the south. Yet, after telling people to move to the south to get out of harm's way, Israel then proceeded to bomb the south in a manner that President Biden himself admitted is indiscriminate. This is the highest form of hypocrisy wrapped in a veil of concern and independent geopolitical analysis by Farid. Farid is one of the most unreliable analysts we have ever seen. He was so concerned about Biden's guidance of the Israeli war machine in Gaza and how concerned he was about the indiscriminate bombing of civilians in the south of Gaza, but at the same time intentionally omitted the fact that during this period the Biden administration supplied millions of shells and bombs to Bebe's army on top of more intelligence on targeting and destruction. Why didn't Farid make this observation? Why was he intent on making Biden look good and Israel bad? Everyone knows that it was the same administration that famously rejected an actual ceasefire in Gaza three times. We mean an actual ceasefire that would have made it possible for a permanent cessation of hostilities in the Strip and even totally prevented the invasion of Rafah. Farid appeared to be oblivious about this, or he outrightly wants to use the secret tool of deception to shore up the failing position of Biden in the upcoming elections. You see, we understand the game at play here. Biden has faced serious backlash from Arab Muslim voters and American Muslims in general. They have threatened to abandon the party, which has supported the actions of occupation forces in Gaza. They blame the administration for not doing enough to aid the innocent in Gaza. And by the Trump-like support the administration has offered Netanyahu in the face of his army's brutality in Palestine was a scandal for them. There's a serious rethink of their support, the rationale behind voting for a man who does nothing at least to enforce a ceasefire. Despite the appearance of the inability of the Biden government to stop Bebe, they know that it's all games to continue to undermine the people of Palestine. Farid knew all this, but this upcoming take landed him in shallow waters. The U.S. has repeatedly pressured Israel to make greater efforts to protect innocent civilians, but to little avail. Now it has been counseling against an invasion of Rafah, the city nestled close to Egypt, where over a million Palestinians have huddled together. Prime Minister Benjamin Netanyahu has promised to invade Rafah, whether another hostage deal is made or not. Washington has warned that after the war there should be no Israeli seizure of land in Gaza and no new Israeli occupation of the territory. The Israeli government's plans are to do both. The result is that American policy on the Gaza war now appears hapless, ineffective and immoral. The image of U.S. officials wringing their hands about civilian casualties while providing ever more weapons is grotesque. The image of a precedent of the United States mumbling words like indiscriminate and over-the-top to describe Israel's bombings suggests weakness and passivity. Part of the problem is that in trusting the Israeli government, Biden is trusting Bibi Netanyahu, an exceptionally clever politician who knows how to handle American presidents expertly and has done so for decades. This time, Bibi has outsmarted, outmaneuvered and outplayed Biden. But the problem goes beyond Bibi. Israel is in trauma. The October 7th attack shook the country to the core. The sense of safety that Israel was supposed to confer on its people has been shattered. As a result, many Israelis are sanctioning policies that they will regret deeply. President Biden, as a true friend of Israel, has the credibility to tell them the truth publicly and directly, perhaps in an address to the Israeli knesad, as foreign policy expert Richard Haas has suggested. Sure, Farid, it is hapless, ineffective and very immoral. Does this sound familiar to the way this administration has handled another crisis in the world? There is some recent crisis that instead of seeking a negotiated settlement, this administration opted for violence. It supplied arms, training and diplomatic support. Yet the effort came to nothing as it became apparent that the crisis can only end at the negotiation table with even bigger compromises. Can Biden simply look in the mirror? Here is the deal, Farid. Nobody believes Biden's beloved Farid Zakaria would ever throw such type of big words at the policies of this administration towards the crisis in Gaza or any other crisis in the world. People were caught by surprise. Farid used words that are reserved for people like Trump. He actually meant to show that the American public and, of course, Democrats are fed up with Netanyahu's war and with the growing call for a ceasefire. All be it technical, there's a need to give Netanyahu the impression that the legacy media, which has been largely silent in the face of alleged cases of genocide in Gaza, is leaving him behind with a more robust revelation of the truth. Without the big media, Netanyahu would have lost the information war.  But will Netanyahu budge? He might not. He understands the hypocrisy of American policy sometimes. He knows that the sudden call for a six-week ceasefire might be an alleged plot to remake the image of the administration in the face of mounting electoral predicaments. So anything can be done to save the face of the administration. So he might continue the fighting and even if he doesn't, maybe for the sake of a temporary ceasefire, he would resume it. Farid needs to take back his words. No one is deceived. About one in four people are on the brink of famine and almost all are dependent on food aid. As of late December, the water supply is 7% of what it was before the war. Most of its hospitals no longer function. A visiting Oxford-based surgeon, Dr. Nick Maynard, described the condition at a hospital in Gaza, one of the few that are partially functioning. Quote, we saw mainly a lot of children coming in with the most appalling injuries, many of whom you knew were going to die and you couldn't give them pain relief. There was often no morphine. There was nowhere for them to die in dignity. So often they were just literally left lying on the floor of the corner of the emergency department to die. Israel says its goal is to totally destroy Hamas. You can kill Hamas militants. You can uproot its infrastructure. But you cannot destroy Hamas totally because it is really an idea. The idea that armed resistance is the only way Palestinians will get their rights. To defeat this idea, you need a better one. A way to show that nonviolent action and cooperation would lead to better lives for Palestinians and lasting security for both peoples. And Biden should go to Israel and show the country his love for it by speaking these hard truths. He would also show America and the world that he still has the energy, moral clarity. Many fails to grasp that this video underwent vetting before its publication. Its content aligns perfectly with the administration's narrative. We are not to blame for Israel's refusal to end the war. We've exhausted diplomatic channels, even leveraging reliable allies, yet Netanyahu remains obstinate. Frankly, there's nothing groundbreaking about Fareed's commentary. It neither staunchly supports Palestine nor vehemently opposes Israel. Rather, it's a calculated move aimed at applying pressure on Netanyahu in the short term. The broader geopolitical landscape remains unchanged, including the ongoing conflict. Its analysis serves as a face-saving measure, plain and simple. Thank you for your attention. Please consider sharing and liking this news update with your loved ones.

Good morning everyone. How are you doing today after all the social activities yesterday? All good? Cool. Welcome to our session on designing the future of the Drupal admin UI. So my name is Sasha Eckenberger. I'm a designer at UNIC Swiss company in Zurich. I'm Sasha Eckenberger on all social media so yeah just follow me everywhere. If you have a hard time to pronounce my last name it's quite easy it's Ek and Burger. So yes. Hi everybody. Hi to the new ones here. I'm Cristina Tomillas. I'm a frontend developer at Lulavod. You can find me on Drupal.org as a screener. Your turn. Hi I'm Archita. I've been working in Drupal for four years. I am a UX designer with security. What are you doing? So we are going to talk a little bit about initiative in general. Also we're going to talk about claros that probably something it's the reason why a lot of you are here today. We are going to talk about the design system. Sorry we are designers so that's mandatory. We are going to show you some things some new things that we are working on. You can take photos but just be sure that it's work in progress you will see later. Also we are going to ask to you if you want to come and join us and help us and some data later. So let's start with the initiative. The first thing is why did we start? I'm pretty sure all of you are aware of the why. So the Drupal administration actually wasn't refreshed for years. It's not that it goes a bad design. It's just that it goes like eight years old or something like that. Even Drupal 7 was using 7 and Drupal 8 was using 7. So yeah it was the time to to make a change there. So that's why this initiative started. It goes initially the JavaScript modernization initiative and later the admin UI and we came together and created the whole initiative. So more or less about the initiative it has three main parts. One is the the JavaScript modernization. The other is the design one and also there's the user research that was mostly happening at the beginning like with Suzanne that is there and a lot of other people. And the three parts it was a little bit complicated because each of us were working on completely different things and we had to come together and try to find goals that were kind of less similar but each of us made stuff that get into core and we were trying to make things better like for example the new design system, the new editorial role. So those are all of them things that are working progress. So in the short term we are planning on updating the existing admin UI. So it means that we are replacing 7 with a new clatter theme but it's going to be the same admin UI so far. In the longer term the goal is to completely change the UI. It's going to go to be step by step probably and when I say completely change the UI it's not that it's going to be like something to make pancakes or something like that. It's going to be a UI for managing content. It's just that we are trying to think big and trying to change the layout on these things but you know you can't completely change someone's interface from one day to another. So it's going to be a longer term. Good. So Claro, who has heard of Claro so far? Who has used Claro? Who is still using it? Good. So I'm happy to announce that we have over a thousand sites already using Claro. So that's quite a lot. So for the few people who have never seen it it looks like this. So basically everything you know from 7 is in the same place as it was before. We just refreshed it with the design system as Christina said before. We have all the same regions but we had to take a lot of consideration in the design. So basically adding layers to give more depth for different elements or also making some elements bigger more room more white space. I know a lot of people don't like that maybe but we might have something in hand later for that. Then we have yeah you see I just go through some designs so you can see everything is still there where it used to be. It was just basically us trying to adapt the design system as quickly as possible to the administration UI. One important thing was that we make them the mobile experience better. So what do I mean by that? So basically just like making sure that all the elements are like have enough room to click so you don't accidentally click something you don't want to. Also like increasing the text size so it's easier to read on mobile for example. But I think the most important thing for Clara was accessibility. So we did a lot for accessibility and not only in the front end so we started quite early in the process. So when we started to design or redesign component by component we already took in accessibility maintainers and other people to that we already have like the first iteration for the design from an accessibility point of view that we have like an improvement to what we had before. One of the things which took us a while to figure out how we want to do it was basically like the focus for elements. So by implementing it the way we currently have it like with this green outline which is basically just like a color which is only used for focusing an element. So this gave us quite a good feedback from all the accessibility maintainers and also in our tests. Then we also increased the contrast so to be compliant with like standards like WCHE 2.0 or 2.1 we increased all the contrast for all the different elements like the text and also like contrast for input elements and so on. And there was also quite a huge involvement to improve the experience when you're basically like in Windows High Contrast mode for example. So there was like a short demo on Drees Note if you have seen that. So here you can see like a bunch of components where we like explored how the focus ring that's basically what we call it could potentially work like and like most of those elements are already implemented in that way. Okay so how we did get here? So we started like a long time ago and we have our first version of Clado around February and then we launched the first alpha release when we had the few components like batons, fields and several things and I gotta say they were the first version because we've been iterating on that for several months. We launched the 5th, the 5th alpha like in September and after that the goal was going on experimental theme in Drupal core. It means that we needed to have a better release done before the code freeze for the 8.8 version of Drupal and we had to reach a specific goals before that in with enough time to have this better release and then getting the core committers and project the product managers and also the framework release managers and everybody reviewing it with enough time to say yes we approve it and we will make to Drupal core but it was really hard the last few weeks because all the feedback came at the same time and we were late so it's been to say that rough which last two weeks before that and now that we are experimental theme in Drupal core if you are using Drupal 8.8 you still can use the country module theme if you are using 8.8 it's in Drupal core as experimental you have to enable it and our big goal here for Claro is getting as a default onion theme at some point for Drupal 9 but first we need to reach the stable release before and ideally with more time this time for that we have a roadmap. The roadmap had several beta blockers that we reached at the end so and after that we have several boxes with several kind of features that we need to have down before we reach stable so we have new features we have a lot of accessibility issues that we need to fix a few UX improvement design improvements also some technical depth that we had to move from previous issues and try to break the issues and made them smaller to get that done right now we have like nine box but it doesn't mean that it stays like that if you please can try Claro and if you find something please report that into Drupal core because the sooner that we get the box the sooner we can start working on them add them here and get it done before the stable one and a part of that we have several features that are should have or could have like for example changing the the font size and these kind of things that will be really cool but there are a lot of other things that are more important right now so that's more or less the roadmap that we have ahead of us and that's what we need to do before getting into a stable release and we need your help for that so please test Claro and report the box we wanted to have a comprehensive Drupal design system basically a single source of truth where all the elements are grouped and collected for anyone in the future to come back and help us and work with us on it some characteristics some traits of the design system we've built very fresh very accessible like Sasha rightly said that accessibility was our primary concern it is absolutely user friendly and is robust it has a strong foundation and it has the potential to evolve over time foundation has color typography and space in our design system we have we modular scale has several implications we chose this as it we plan to move towards variable fonts and fluid typography in the future so setting one base value which is 16 pixels helps us calculate all other by multiplying it by 1.1 to 5 we are using system fonts for this all the colors the bright bold colors you see here they all achieve triple a access accessibility modular scale for this as well this is very well documented in the specifications of Figma we are working on Figma in the future we plan to make a style guide but for now everything is on Figma the design design system has a collection of components and it it has all the use cases of components where we have everything from radio buttons to drop downs and everything else based on seven seven refresh we came up with components that were already there and would work as a fallback right now we're focusing on coming up and building and designing components that are needed for claro and also for the next generation ui for example this one one is a drop down that we used for refresh and the other which also has jits we planned to do that in the future in the new admin ui exact so story of a button yeah christine now we want to jump in and talk on the story of the button you got me here okay um you might say button is bad on me what does it have it just have some text and something maybe a background maybe a border in there well it actually can be wrong it can be square it can have several colors it can have icons it can not have borders it should be accessible so we've probably tried five fifty seventy versions so we've had for sure at least twenty final versions like the one this this is final okay final two okay no final final two three yeah so and actually we had some of them committed and then we had to well do some changes on there so we've had several um iterations on there and that's the bad thing that's not the only button so you see here we have the default button we have the primary button then we have this super cool secondary button but where can we use it so we have a lot of um things to take into account here we are going to change some things in the future not I'm sure ten more buttons I'm not sure but that's not all we also have messages in Drupal Goren it's like a message is a message what what's wrong with that well um you can have a lot of variations on that um you can have really long messages and really short messages and you can have the three messages together you maybe can have a new message which is the status one you maybe want to have uh something small on the left you maybe want to line messages you maybe have I don't know there are a lot of options but the most important thing is that you want that you want the message to be seen by the person that is using your interface so the final messages that we got in are a little bit different so these those are the messages that we have right now the first time that we saw that it goes like oh black messages are you sure we have a super white and clean space that's actually how how many of you know what clado means are you here you know what's clado okay come on yeah say light well light or that has more space clado is a Spanish word for light or lighter or something like that so yeah that's the thing and the messages are super dark so yeah it goes quite a shock at the beginning but it really worked and a lot of people actually gave good feedback of that we might still need to change some things like maybe I've got some several things but as we stated this we are planning on iterating on iterating on all the designs and everything so if you have something to say about that please just come to us say what's the problem that you're finding and we will make this better want to jump in or I can continue okay so we have also several new components on clado things that weren't there before that for example another button so as you can see the most important thing here is the red one on the bottom that is the delayed one what's the history behind it so the thing is that it's not a button it doesn't have the markup of a button so it can't look like a button on an accessibility point of view in several other ways because it is not a button right now maybe on a future javascript ui it could be something that actually have an action on the same page but right now this is a delete action that takes you to another page so that's a link that's not a button but that's a button it's with the buttons so we had to come up with several components like for example the beijer and these kind of things we also introduced a new component that it's cart I think it's a most used component on most of the design systems that you can see but we didn't have it so we actually created it and it's used on the appearance page so you can check it there um the action uh the icon uh link it's a new kind of button we are basing uh part of the design on something that goes already there which is the quick quick edit but we're probably going to use it somewhere else no spoilers yet so you will see some new components that we are planning to put in are the the chips you can take the photo now if you want so probably the range input and several things so the the idea here is that we are going to introduce new features and new components by the time so it's not all at the same time um there do you want to come up with this one okay so the specifications for that are um everywhere you can check it uh uh on figman everywhere okay so um um everybody can check it uh on figma you just have to go and check the link we are using a really um new like from the last year's collaborative tool for design uh we are planning to use um a style right online at style right at some point we really need to have this conversation but for so far all the specs are on figma or on the issues that we create on claro so what's figma um figma is like google docs for designers that's the easier way of explaining it for us was like a completely new change and that's something that led us um work together from people from all over the world different time zones and it was super easy so if you want to see what's a designer's party it more or less look like that so you can actually steal someone's idea and make it like it's yours and make it better so design party you can check the designs here that's a url uh it's public to anybody you can actually see it if you are logged in figma you can actually um check the color check the phone sizes and check everything and if you are a designer just come to us and ask for permissions we'll let you play with everything and please help us because we really need designers so come and join the party so we now saw a lot of things you might already saw in a while right so like everything which is um basically like implemented or in one way or the other into claro um but now i want to show you basically just like an outlook of what's beyond that so what we are also working on so while working on claro and also the design system in particularly we came across a lot of small things we wanted to change but we weren't able to because we had to restrict ourselves because we didn't want to change too much for claro um that was for one fact that a lot of more people need to be like bring in to do these changes and on the other hand it takes a lot of more effort and time to roll out these changes um so the proposed layout changes here um is basically this is just like a stripped down wireframe of how claro looks today like the node edit form and now we have like several things like this sidebar on the right with the settings which is actually not the sidebar it's part of the content and also we have a toolbar on the top uh which can also be limiting so we were thinking why not rearranging things and make them in one way or the other better um so basically like having different new regions and different new elements to work on um so the sidebar for sure can be basically like collapsed and expanded as you also see on other cms's i mean it's not a pattern that we invented it's out there for quite a while um so this would be like the the new toolbar concept that we could potentially as i said like this is all highly um work in progress and maybe we work on it maybe we will just you know screw it and do something else it's just like something we were thinking of um so potentially it could be that the sidebar is on the left and for rtl user it would be then on the right um and so on um there is this new sidebar region uh which is this here which can contain all the settings so this is not maybe limited to the node edit form so this could also be potentially be used in other places in the admin UI just to concentrate settings in basically uh one column or one place um but i think the most striking one would be the sticky action bar um so basically like having a fixed header or a fixed element which gives you always like a clear call to action so if we take this node edit form as an example you would always have the safe button on hand so you don't have to scroll like i don't know like a lot to get to the safe button if you just wanted to change the first element uh on the node form for example so just like providing uh more feasible options um so i did some design markups in the past couple of weeks and also these two guys gave some feedback and so we we did some small iteration but this is really a work in progress you can take pictures but you know just it won't be there in any time soon just saying that um so this could be basically like an overview page with like a table of content so like having uh content in there so it's familiar but it looks a bit different it has a call to action on the top to create new content uh everything is a bit more compact but still um in a nice way shown um like the node edit form with more depth with more clear separation of different elements like the sidebar the content the sticky bar at the top and then maybe a potential implementation of the new toolbar now you're saying blue isn't your color there's too much spacing or too less spacing or whatever um we get the points um so something we're also taking into consideration but which was basically just like out of reach for claro um which could also potentially be there in the future or like personalization options so if you don't like blue you might change just the accent color to something else like red or green or you name it just something else for example like these could be colors you might use or might want to use maybe not maybe others um then it could potentially look like this or maybe like this if you like orange or red maybe pink yeah you get it like having more personalization options also like spacing settings so one of the feedback for claro was that we were using too much white space so seven was more compact that's actually true but there is also a reason behind it there's already like an issue on drupal.org um were like there were like things proposed how we consult that so this could also be potentially like a setting in the future in the ui so you can reduce it um the same goes for um motion so if the new ui has more like interactive like interactiveness um then we could also provide a reduced motion setting um like from an accessibility point of view or you just dislike everything like being nicely animated and transitions um also even going even further and making like high contrast as a setting so that you don't have to force your system into high contrast mode but you can force the ui into high contrast mode improved rtl support um so i did this mockup so i use google transit don't blame me if there is anything wrong on this one here um but as you can see so this could also be potentially like a setting so you can set the whole admin ui to rtl and then you have everything in the floor you're used to right so like the cyber moves to the right and so on so there are many many many options possible and i think we discussed um all the three of us and also with uh other bunch of people we discussed a lot of possibilities we wanted to do but we restrict ourselves for now um but there's one more thing i mean it wouldn't be 2019 without showing this right so why not having a dark mode right why not just having a dark mode well the implementation is not that easy as i just say why not having it takes a lot of effort to do it but this could also be potentially like a change in the future so if your whole operating system is in dark mode why not having automatically the ui in dark mode or making a setting that you can turn it on or off and also here we could have accent colors so which match your system or your preferences so this is all exciting at least for me as a designer doing a dark mode is always exciting because it's a trend and i really like dark interfaces but we have to keep in mind that this was all highly experimental and we're just like started figuring out what we want to do in the next couple of months and years so it's a long way to go but we were just like quite passionate about you know just showing you that we have something else in mind that just like the claro is basically the end so it's just a start okay here's where you come in so we really like to have people testing claro helping claro getting involved it's not so you can help in a lot of ways if you're a designer or you know a designer that knows a little bit of trooper league will be great even if they don't know trooper please come and help if you want to help on issues um recently because it's an experimental core right now in trooper in core you just have to go to the issue queue to the from trooper core check claro theme as a component that's a url if it's easier for you and find four issues that are active and need gorg or just reveal them or i don't know few issues because you found the bug or something so designers please come and join the design party and those are the slag channels where you can actually join to do both slag um we have the separate party for designers and then all the rest of the people are welcome into the other one unless you want to come and rest pink or black or something else um actually the admin UI a lot of things are discussed also about design and how to implement things so everybody's welcome anywhere um you can join the admin UI ask for permissions for figma the the admin UI design and ask for permissions for figma the admin UI channel and just jump in and ask for help or whatever so we meet every wednesday at two two and a half in europe uh in central europe um the chats are usually the the meetings are usually chat only so if you are working and doing something else you can just follow it say hi i'm here just laughing or something like that and just read what's going on and uh yeah that's it that they are just chat only so anybody can just jump in uh they're in english but since it's uh written so anybody that it's not proof that english can also help and please come to the um uh springs tomorrow or today they will be on the tables also on the springs um say how you want to contribute we will meet people also writing documentation and i don't know whatever you feel you want to help just come in there and we'll figure out good so um let's summarize what we saw um we have a thousand sites or more using claro um you can insert insert it as a as a contract module or uh it will be as available as an experimental theme in drupal core so just use it and give feedback find box and other things everything is welcome just make sure you test it um accessibility is important and will be important for everything we do in the future um so this is really like the foundation of the work we've done for the design system for claro and also for everything we do in the future and there is new stuff in the murk so claro is not the end so uh there's a lot of things to come and a lot of things to fix and a lot of things to figure out how we potentially can do it and implement it and yeah just be excited about it and help us together to build it um yes so one important thing to say um all the gifts were treated safely and nicely so no gift were harmed during this presentation just as a little site note so uh thank you very much um we're now here for questions if anybody has questions thank you yeah that's probably so this might be sorry this might be uh the beginning in the weeds a little bit but for example on the uh with the error messaging uh all of us have encountered uh errors that go down page down page you know this this long has there been any thought to you know restricting them and they'd be having it expand over the click so that you don't get lost in the error so so messages history okay so um well even going further in time so before that we uh did a lot of research and one of the goals we we didn't go that far on the explanation of the three parts of the initiative but on the ux part we defined actually um so several things come from there like for example we ideally in the future will have how to save and this kind of thing so a lot of things can happen there and one of them was our goal was to solve mainly um content outdoor uh editors problems all right so very few times an editor is going to see this huge message so that's a main goal so when we actually decided what was the best um design for messages we're taking into account the length of the messages so you as an editor not as a side builder you're not going to see that huge messages we had several proposals where actually the messages could be toggled what's the problem there it's the structure of the data of the messages how what at what point do you actually crowd cut the message three lines four lines at a certain point do you let the system define what's the title because that's one thing that we actually discussed on our ux meeting let's give the messages a title but it's like a lot of messages don't come even from the database or something like that so you won't never have a message as something so it was super difficult to actually define that and where do you cut the messages you define that for desktops then for mobiles then for so we ended up just saying okay these messages right now are they going to have a limit because of course we need that long messages on on for site builders but for content editors right now that's enough it doesn't mean that it can't be improved that's actually one of the points to improve the time so hi there hi i'm just just a short point on that i think actually dealing with the length of the messages is also a task for actually working on the text because we have lots of text ui text that is way too long so the question would rather be to make the text to show that it works but the other question i had because i really like the fact that you want to look into the toolbar as well would that also be the moment to actually rearrange the toolbar because we have some 3.7 legacy still in there like the content page where media items need to live on the content page and other content is under structure so put that the right moment to say okay let's change that as well so um this is also a really long conversation and we already have this conversation so the thing here is that don't touch my drupal is usually a point that a lot of things a lot of people is going to say to you if i'm used to something i don't touch my drupal don't change me the things from where i'm used to get them so yes um some of the conclusions that came from the the study that we made on the ux ux side of the of the initiative is that um you end up with a completely different uh toolbar when you are a content editor and a lot of things are inside the the content tab but then there are some things inside the structure and sometimes some things inside the configuration so yes ideally we should change the information architecture of the toolbar but where do we place that limit are we actually focusing ourselves on site builders which is people that is going to work for one three months two years on a site after that content authors are the ones that are going to live with that drupal site so we're really so one of the proposals was actually having separate menus and have a different role a new role for site for content authors content editors i think we ended up with a name so yeah the thing is that one of the proposals that we were talking is maybe we just move some stuff inside the content tab and then configure differently the other tabs so maybe first thing what the structure what goes inside the structure what goes inside configuration and so on so yes that ideally should happen i don't know when because you don't want to break the also probably in a country module first and then i don't know it's it's on the ideas issue queue if you want is we want to jump in please go into ideas issue queue is um drupal well it's project drupal daja daja ideas so just look for um uh what's the name of the issue don't remember well it's we'll try to find that there so it's uh it's in there already so you jump in and propose anything and get involved if you want to help there great talk uh will uh will it be uh compatible with internet explorer 11 i know i know it's bad but it will still be supported for like six years instead but and uh like uh related to that uh what are the techniques used are the is it already in css grid and css variables or whatever you want to call them do you want like you mean like the new stuff you saw yeah the the new cloud theme is it is it built with a grid for instance it's not built yet so oh it's still to be defined yeah yeah so um yes it's fine so uh claro is in drupal core so it will comply with all the core standards so yes it will be available will it will comply with uh i11 yes um yeah maybe lori can say no about the grids uh well you want to jump in it's not that we are using grids it's just that so about about uh is this about the browser support policy so we have a new browser support policy in 8.8 which drops um uh very old browser like like such as firefox 25 which is probably from 2013 uh which you can install on your most recent mac and uh so we do support the browsers in fact and we do have now a browser support policy that we comply with and uh about the grid we are not using css grid and we're using flexbox instead and we are using the css custom properties but and we use post css for providing a backwards compatibility layer to i11 or a polyfill it's yeah that's what we do and in future when we drop support for i11 we can get rid of that post css plugin and use the css custom properties the way they are supposed to be used so so i know you're using big mouth now for all the design and i see all the activity in big mouth there's a lot of comments and then you're also talking about having a like a style guide that's separate um and i heard that like yesterday tim plunkett was mentioning in his talk about maybe having a different way of integrate better integrating the design process into drupal.org i'm wondering if you have any thoughts about what would be a what what's needed there so are you mentioning uh the report that's our workflow or in general just in general like what's what's missing from the current design process to uh make the work of the design maybe more visible or more integrated with the rest of the so the design system ideally will be completely separated from cladrum and it's not that it it is just for cladrum in theory for the new javascript or let's figure out what's going to happen there but then anything that it's going to touch the aminui in theory is going to follow this um design system the thing is that it will ideally be online and accessible we haven't had this conversation yet so there's an issue uh on it goes on cladrum so now it's going to be on on the core issues about using storybook that was the first idea we really don't know what's going to be the end of that the final solution so we haven't figured it out how to integrate with drupal.org and conversation is going on any more questions so uh focus on accessibility is obviously very important uh color contrast you mentioned specifically but then you also mentioned in the future you're going to give people a tool to change the colors and they may unwittingly break all that hard work and it might not even be done by a conscientious engineer or designer they may have like some CEOs that over them saying make it fit the brand guidelines and are you going to give them any tools to push back against that like like like with password strength where you say this isn't secure enough you could have one saying if you do that you're going to scare people I see you're a little bit um are you following the color issue on ideas I will be in okay there's an issue so there's an issue right now on the ideas issue queue about deprecating the color color module um it's not that we don't want people to change the colors is that probably colors is not the way the way that color the color module is letting you change anything it's not the best way to actually have variations in color for a palette like let's for example let people change the color for the bottom and you have a brand uh policy that says those are my four colors that I want to use right now the color module don't let you just choose between four of them it just gives you the whole spectrum for color so you can have the anything there so yes ideally ideally there should be this tool i'm not sure if based on color or an evolution of that because it's not only us also the new frontend theme olivero is going to use something like that so um um it's going to happen how we still don't know how extensive has your user research been your user testing and so on okay so um there we had several um steps there uh um you want to answer you want okay so um yeah there's several people here that were involved um so we did the first survey uh i think two three hundred people answered the survey so what were the main point pain points on the coven ui after that we did a card sorting uh yes the card sorting uh where we actually were trying to figure out what should be the information architect that we were mentioning before um it turned it turned it out that people were actually answering uh with the same structure that they know right now from Drupal so it really wasn't really useful and after that we made several tests on the current ui to see um what was the the best layout because we had several proposals uh in the past that were close to kutemberg and right now it's not exactly the best way of changing the current new ui so far so um that's more or less what we did so mainly from the survey that's most of the um information that we have good thank you again and we're around just ping us if you have any more questions thank you


Hello guys, good afternoon. Good afternoon, Ritik. Who all are there? Please type in your name. Only two of you, Ritik and Visist. Where are the others? Okay, hello Saimid. Have you started preparation for board exam? Okay, Visist, your exam is already going on, right? Okay.  So today also, we are going to discuss a few questions that is, you know, board level questions only. You see, the first question like the one marker, what is the answer? IOPSC name. Two phenyl ethanol. Others tell me the answer. Two phenyl ethanol. Okay. Again, you see Saimid here. You have written this two phenyl ethanol, but there should not be any space. Okay. So when you write down the name, the answer will be two phenyl ethanol without any space here. You should not write any space between this phenyl and ethanol. Okay. That you must take care of, otherwise you'll lose your mark. This question you tell me? We'll see some reasoning question also today. No, it should be small only. What is the answer answer? Tell me the name. What is the IOPSC name of the structure that you have written? What is IOPSC name? I am not getting any response, guys. Done. What happened? Tell me. Okay, I'll write it down. You see. Write the structure of an isomer of the compound, this which is most reactive towards SN1 reaction. Okay. So first of all, we'll try to, you know, find out the degree of unsaturation. Okay. However, in this, this is a board level exam. The board level question only one mark is there. You don't have to, you know, find out, show this DOU, degree of unsaturation there in the answer sheet. Just you calculate it for your own sake. Like for this one, you see four plus one, the formula we have H plus X minus N divided by two. So the degree of unsaturation is zero. Means there is no double bond or triple bond or ring present here. It is an alkyl halide. So since SN1 reaction we have, and for this, you know, the alkyl halide must be what? Tertiary. Tertiary alkyl halide. So here you see the structure would be CH3C, CH3, BR, CH3. Why it is tertiary? Because, you know, for SN1 reaction, it follows by the formation of carbocation and tertiary carbocation is more stable. So this will be the possible structure. Okay. Understood. Next question. 10 minutes one. PBNO3 on heating gives a brown gas with no dimelization. Okay. Answer is correct. It's NO2. And the reaction will be what? This reaction you have to write down. The reaction will be PBNO3. Heat this, it forms PBO plus NO2 and O2. This is not a balanced reaction. So this NO2 undergo dimelization and forms N2O4. So the answer for this question will be what? NO2 is the gas. Right. This reaction you have to write down. If you memorize last class also that we have discussed in one more question, they have asked one question based on this reaction, this kind of reaction. There we have P4 when reacts with some compound. If you remember HNO3 or something. Right. So one reaction based question they ask here in one marks. What happened? Why you are messaging? Just let me check it. Okay. I saw some messages now. Okay. I could not. The message was not, you know, reflecting over here. Just now you saw your messages on your WhatsApp. Anyways, anyways, that's why I was waiting. Yeah, correct, correct. So this is the answer for this question. Now, the next question you see, this is again you see, this is sixth number question. So I'm not discussing all the questions, right? Two important questions which is there. I'm just discussing those. This is two marks question. Do this one. What is the unit of K and order and molecularity? Order is zero. Molecularity is two. Yeah, right. Zero order is correct. Molecularity two is correct. Unit K unit you already know. Second inverse mole per liter one minus N where N is the order of the reaction. Okay. So this you see, like I said, order is a experimental quantity. Okay. So you cannot, you know, find it theoretically or mathematically. It is an experimental quantity. Right.  Right. And there is no any rate determining the step in photochemical reaction. Right. Like in this case, as 2 plus CL 2 reacts from HCL in presence of light. So this is again, photochemical reaction.  And in chain mechanism, there is no any rate of reaction determining the step. Okay. Hence the rate of the reaction is constant. Right. Rate of the reaction will be constant. Hence order will be zero. Molecularity is what? One molecule of H2. One molecule of CL2. So molecularity is again one plus one two. Right. And then the formula of K we already have, which is this formula is liter inverse, sorry, second inverse. Here we have second inverse mole per liter one minus N where N is the order of the reaction. One thing I have mistaken here, this should not be second, this should be time actually. Right. Time would be the correct one. This can be anything second or minute anything. So when order is zero, the unit will be mole per liter time inverse. This is the unit of K we have here. Right. So order is zero. Why zero? Since it is a photochemical reaction. Molecularity is two. This is a very common question. The difference of order and molecularity for both point of view. The difference between order and molecularity is a very common question for both point of view. Okay. Next question. This one. Right chemical equation involved in following reactions. Hoffman bromide degradation carbide amine reaction. What is Hoffman bromide reaction and carbide amine reaction? What happens in this reaction? You can write it down. What is Hoffman bromide degradation reaction in Hoffman? Okay. All of you have done. You see in Hoffman bromide reaction, amide reacts with bromine right in aqueous or ethanolic solution. Right.  Primary amine. Amine. And in this what happens the amide, which is R C double bond O NH2. Amide is allowed to react with bromine in presence of NaOH. And the product we get here is R NH2, which is one degree of amine plus Na2 CO3 NaBr and then H2O. This is the product we get. So we will get primary amines in this reaction. Okay. Hoffman bromide. Carbide amine what happens in this? Little bit of theory of this also we write down that what happens in Hoffman bromide that you write down first two, three lines and then you write down the reaction. Similar thing you do with carbide amine reaction also. In this what happens, aliphatic or aromatic primary amines with chloroform. Right. So we can have this R NH2. This should be also primary, but this can be aliphatic or aromatic both. Primary amine. Can be what? Aliphatic or aromatic. When this primary amine is allowed to react with chloroform C HCl3 in alkoholic KOH solution. It forms carbide amine RNC isocyanide. It is basically carbide amine is nothing but isocyanide which is 3 KCl plus 3 H2O. Yeah. So this primary amine can be aromatic or can be aliphatic both. So this you must remember. So whenever you have any name reaction like this, first of all you write down the statement of that reaction that what happens in that reaction. Okay. Then you write down the reaction like this. That is the best way. Okay. Okay. Next question you see. This is again the logical question. The next one I'm giving you. Do this one. Gas A more soluble in water than gas B at same temperature because the following two gases are higher value of KH and Y. Okay. So see actually what happens here. The Henry's law according to Henry's law if you discuss. What is Henry's law? We have two, three expressions here and we can write Henry's law is supposed to work. The concentration of gas dissolve. Right. So concentration I'll suppose I'll write C only concentration of gas dissolves is directly proportional to what pressure of the gas. Right. So when you remove this proportionality sign C is equals to KH into the pressure of that gas. Right. Where K H is what? K H is the Henry's law constant. Okay. Now what happens? The question is which one of these two gases have higher value of K H. Okay. So what happens if K H increases when this K H increases solubility should also increase which is nothing but the concentration. Right. If the K H is higher, it means the concentration will high. And then we can say the solubility will be high is high with higher K H value solubility will be high with higher K H value. Correct. So you see here it is given the question of following two gases have higher value of K H. So the gases will have higher value of K H will be more dissolve. Right. So since A is more soluble in water, so we can say the K H value of gas A is more than to that of K H value of gas B. Right. This is the answer of the first question. Second one is again, you know all this maximum boiling as you throw shows gas B should have higher K H. Just a second. Gas A is more soluble in water at the same temperature. More soluble means more will be the concentration its partial pressure is more solubility decreases with increase in K H value. More solubility lessens the partial pressure. Is it? See all the gases dissolve according to its own partial pressure. Yeah. So higher will be the pressure more will be the dissolution of gas partial pressure I'm talking about. Higher will be the partial pressure. Easier is the dissolution of gas. Just a second. If these was to K H X into right. Okay. Okay. Just you this question. I'll just come to this question again in five, 10 minutes. I'll give you another question. I'll think on it. Okay. Let me think on it once you solve this question next one. You do this one. I'll just come to that question again. Question number eight will do it again. Just you solve this question first. Well, a coordination compound is mixed with a GNU three three moles of this right the formula. Done. Okay. So there are three moles of agCl precipitated. Right. So three chlorine atom must be outside the complex square bracket. Right. So the formula of this will be co NS three whole six. And cl three will be outside. Okay. And the name of this compound is. It is hexa mine. Cobalt oxidation is says is status three. So hexa mine cobalt three chloride. Yeah, correct. The answer is correct. Okay. Okay. Next one you see question number 10. Then we'll see some five marks question. This one. Then we are F three. The hybridization will be seven into four. That is 28 28 by eight is three. So three bond pair and two lone pair for BRF three for BRF three. We have three bond pair and two lone pair. So steric number is five hybridization is SP three D. Right. And what is the structure. The shape will be what T shape. If you write down XZF four. In this, the number of lone pair and bond pair is what eight 36 by eight. So we have four bond pair. And two lone pair. Right. So the hybridization will be six is a steric number hybridization will be SP three D two. Right. The geometry will be what and shape will be what the square planet. Here the shape will be T shape and geometry is what diagonal bipyramidal diagonal bipyramidal. Okay. So this is the first part. Now you see the second question. The second part of what happens when as to gases passed through an echo solution of Fe three plus salt. Okay. So what happens this Fe three plus salt in that the sulfur dioxide act act as a reducing agent. Right. And it reduces Fe three plus two Fe two plus right. So this S O two here S O two act as a reducing agent. And it reduces Fe three plus two Fe two plus. Most of you have written the same thing. The color of Fe three plus is red, which is not required here, but I'm giving now, but color of Fe two plus is green. This is a color change. Right. And now what happens the last part X E F four reacts with S B F five. Okay. The product that we get here is X E F three and S B F six. This is the product we get. Right. So all these Zenon Zenon fluoride that we have act with Lewis acid. Okay. So Zenon fluoride act with Lewis acid and forms complexes. So this is the reaction we get here. Got it. Yeah. Right. We get the complex. Next one right down the product in these reactions. What is the product we get here? The product is tertiary butyl iodide. The first one will get tertiary butyl iodide. And then we'll get methanol. Okay. So all of you are getting the same product. What about the second one? Then the second one. Is it butene to butene? The first answer is correct. And what happens this lone pair I'll write on here only. This lone pair of oxygen takes this H plus and we get C H three C C H three C H three O C H three. Here we have hydrogen and positive sign. Further what happens here? This bond pair comes over here. We'll get tertiary carbocation which is C H three whole thrice C positive charge plus C H three O H. Now this will take the I minus and we'll get C H three whole thrice C I tertiary butyl iodide. Similarly, when you have alcohol that is two degree alcohol, right, which is heated is in presence of copper as a catalyst. This converts into ketone, two degree alcohol. The product here it will be C H three C H two C double bond O C H three. This is two butanone. Okay. And in the last one, the product will be if you have phenol that is C six H five O H H five. When it is heated with chloroform with an O H and then the second reagent is some acidic acid we are putting in. So this converts into hydroxy benzoic acid. This is the product we get right in presence of acid that aldehyde again oxidize into acid. Actually, you can write down the both product first to get aldehyde which finally converts into acid if it is a complete oxidation we have. Rithik you'll write butane two own or two butanone. Anyone of these two you can write but two own is not correct because when you write but two own, it does not, you know, give the information that where do we have any double bond present or not. Or do we have all sigma bonds there with acid it becomes salicylic acid. Do this conversion. Next question. Do this conversion. Total benzene to biphenyl. Yes, the first one is fitting reaction. What reagent we use here? Can you tell me? It's similar to Wood's reaction propane to Ido propane. How can we convert this propane into alcohol like propanol? Can you convert propane into propanol first and for that what reaction we use into all antimarconic of addition of what? HBR you are using but it is Ido propane. Can you see it is not bromopropane it is Ido propane. Hydration gives you what kind of product? Antimarconic of or marconic of? Okay, then you are using Finkelstein correct, okay. Yes, so with marconic of will you get one Ido propane then? Iodine will be there at first carbon with marconic of? Try that, write it down, try to see. Okay, so to make this Iodine to add this Iodine at the first carbon, right, we need antimarconic of addition. Okay, have you heard about oxym sorry hydroboration oxidation reaction? Hydroboration oxidation, DH3 with H2O2 and all? Yes, so when we do the hydroboration oxidation reaction if you remember this reaction follows antimarconic of addition and addition of OH- and H plus takes place, correct. So when you do the hydroboration oxidation of propane you will end up getting propanol, correct. Yes, you will get antimarconic of addition and OH will attach at the terminal carbon there and will get propanol. When you get propanol then you can allow this to react with HIE, you will get H2O out and Iodine will attach at that carbon. Did you understand this? So first step we can use is hydroboration oxidation and then we will use the reaction of alcohol with HI, clear? Do you want me to write down this reaction? So propane is CH3, CH double bond CH2. So hydroboration oxidation reaction, BH3 with H2O2 gives you antimarconic of addition of H plus and OH minus, we will get CH2OH, right, antimarconic of addition. Now in this if you put HI then H will come over here, H2O will go out and this Iodine will attach. The final product will be CH3, CH2, CH2I, Ido propane. What about the third one? Two bromobutane, two butane, done. Okay, one more thing you see in the 11th C question. Just now Ritik has sent me one image. Okay, in NCRT it is given salicylic aldehyde, right. So the thing is salicylic aldehyde forms when you are assuming partial oxidation, right.  We know aldehyde on oxidation it gives acid, right, that's the only thing. So if you write aldehyde also it's not wrong, acid also it's not wrong. Only thing is assuming complete or partial oxidation, right. But in NCRT it is given salicylic aldehyde, so better you write aldehyde only, okay, that's the thing. Yes, the next question we have 12th, third one, bromobutane to butane, right. So we use alcoholic KOH it converts into two butane very straight forward direct question we have. Okay, next you see here, the next question is question number 13 I guess we will see. Yeah, this one. What is the structural difference between starch and cellulose? What type of linkage present in nucleic acid peptide bond? Okay, correct, correct, right. A few things you have you should add into your answer here. I'll dictate you just write it down. A few points to write down in this. Write down starch is branched homopolysaccharides of D glucose. Starch is the branch of or we can say starch is branched homopolysaccharides of D glucose and contains and contains two types of glucose polymer and contains two types of glucose polymer. That is amylase and amylopectin that is amylase and amylopectin. These are three marks question. Okay, two types of glucose polymer and they are amylase and amylopectin. Now what is amylase? It is a long unbranched chain of amylase. Write down. It is a long unbranched chain of D glucose residues connected by alpha one comma four linkage. Next line you write down. The branched polymer of glucose, the branched polymer of glucose, where in alpha one comma four glycosidic linkage where in alpha one comma four glycosidic linkage joins successive glucose with branched point having alpha one comma six linkage. Okay, cellulose just one point to write down. Like you said it is correct that it is linear unbranched polymer of glucose. So cellulose is the linear unbranched polymer of glucose, unbranched polymer of glucose and you add this line, glucose residues linked together by beta one comma four linkage. Okay, second one you have done. Next one give an example of each fibrous protein and globular protein. Fibrous protein is silk, right? Globular protein is egg albumin. Next question you see. Globular protein is egg albumin and fibrous is protein. Next you see question number 19, we'll see. Question number 19. Solve this question. For the first or third world decomposition reaction of data given here. Calculate log constant. Yes, yes. Log constant means rate constant. Then or trying, yes, yes, yes. If they have even, right, they have written log only it means log base 10. Otherwise they'll mention E over there. Minus two, which is got minus two. Tell me the answer. Yes, calculate the log constant it is given. You have to find out log K. Yeah, log K. What is the value of K you are getting wishes? Tell me just a second. Are you done? What is the value of K wishes you got? Okay, I'll just do this now. See the reaction here is C2H5Cl C2H4 HCl. The initial pressure is given 0.30. And then it is 0.30 minus X. X and X.  So X is equals to 0.20 when you solve this, right? Now since it is given that first order third-worldly competition it is. So we can write down K is equals to 2.303 divided by T log of A by A minus X. A is the initial value. Now when T is 300 what is A minus X? A is this, X is this we have calculated. So when you put this you get 2.303 by 300 log of A is 0.30 and this minus 0.20 is 0.10. So that will be log 3 itself. So it should be through 0.303 into log 3 value is given 0.4771 divided by 300. What is this value? Tell me. What is this value? Tell me. Is it the same 0.301 by 300? Why? It is 0.30, total pressure. So when it decomposes pressure will decrease. X is not the degree of dissociation. It's the X pressure which reduces. Tell me this value 2.303 into 0.477 by 300. What is this value? Total pressure is increasing. Yeah, correct Ramchar. Total pressure initial it is 0.30 because initially what we have? We have only this present initially. But when it when it starts decomposing we are getting two different products C2H4 and HCl. Right, so because of that pressure may increase after sometime when the reaction proceeds. Total pressure 0.59 into 10 to the power minus 3. Okay, so K value you got and then you can find out log K also. Okay, you can further solve this 1.59. So I'll assume this as 1.60 into 10 to the power minus 3. Right, and 1.60 we can write 1 plus 2 into 0.30 which further we can write 1 plus 2 into log 2. Right, so that will be 1 is log 10 plus log 4. That will be log, okay, so next what we can write. I just trying to solve this. This term into 10 to the power minus 3 into log 40 is equals to K. So log K is, I don't think we can solve like this. Can you solve this further? This will be log of 10 to the power minus 3 into log of 40. Sorry, log of whether we write log A plus log B log of log 40. Anyway, so this data must be given here. What is the log value of this you are getting? I'll just do this log of 1.6 you put here. That will be log 16 minus log 10. So minus 3 log 16 is 4 square 2 log 4. So 2 into 0.60 minus 1. So minus 4 plus 1.20. That will be minus 3.8. This is what I'm getting. Minus 3.8 we're getting. If they ask K value, answer will be this log K. You just put log and solve this minus 3.8 approximately you'll get. Okay, so I'm just getting minus 3.3 close enough. Whatever I do not know. You only told me that the value is this. If it is this, the answer will be this. Otherwise you solve this. You will get the value here of K and then you find out log K. It just need the calculation. Nothing else. We'll move forward. One more question we'll discuss on here. The numerical question. Question number this one, 22. Solve this one. Again you see the pattern is again same. In 3 marks question 2 numericals are there. Question number 19 and 22. 23rd is the abstract question and 24 to 26. Again you will get some reactions, series reactions, numericals, name reactions. These kind of questions you will get for the 5 marks. Numerical questions, series reactions, ABCD product, you have to find out into that. And then name reactions you will get. Question number 22. Solve this. Assume universe complete ionization. Boiling point of solution. Boiling point of solution. What is the value of delta TV you are getting? Delta TV is 0.346. Vaishnavi. 0.173 fresh. 0.346. So what is the boiling point then? What is delta TV? Then how you are getting 373 or something? Ramcharan, check your calculation all of you. Yeah, correct. Vent of actor is 2 because MGSE 4 will dissociate as MG 2 plus as a 42 minus. I value is 2. Yeah, 100.346 degree Celsius you got. So delta TV is 346 only, right? 0.346, sorry. Delta TV is 0.346 Kelvin or degree Celsius, right? So you have to find out the boiling point. Boiling point is what? Delta TV is equals to TV dash minus TV where TV is the boiling point of original solvent. 100 degree Celsius in case of water. Okay, so that will convert into Kelvin. So that will be 373. So answer will be 373.346. This is what you are getting. 373.346. Yeah, that's right. 373.173 is wrong. And don't write Ramcharan these solution questions. You don't write the approximate answer. Write down the exact answer that you are getting. Like in this case, it is not 373. It is 373.346 Kelvin, right? When you write 373 only, it means that delta TV you are not considering at all. It is 100 and then it will have 373. That is simple. Okay, so write down the exact value. Don't round it off. All of you have done this. Do I need to solve this? Correct. I'll move on. Okay, now you solve this one. This is electrochemistry. So you will get two numerical questions here. Either from any of these. See, you are getting two numerical questions from physical chemistry. Okay, so the chapter would be solution, electrochemistry, solid state or chemical characteristics. So from these four chapters, you will get two numerical questions of five marks here in the last portion. Solve this question number 25. So one data is missing in this question. I'll just write it down. The E0, these data you see for the second question, B. E0 for A2 plus 2A. It is given minus 2.37. And that is for B2 plus 2B. It is given minus 0.14. These two values are also given. Again, the answer and you are rounding it off. Don't round it off. Why A is better? Tell me the exact value. Don't round it off all of you. Why A is better? Tell me. See, the first answer is correct. This will be 1.99 approximate. You have to find out E cell, right? E0 cell. Formalize E cell is equals to E0 cell minus 0.0591 by N log of product by reactant. Okay. So with that, you are getting 1.99, which is correct. In option B, in the question B, you need to find out which using the following E0 values of A and B predict which is better coating the surface of ion, whether the potential of ion is given. Okay. So here we have to understand for electroplating, we need a cathode couple which gives positive value of E0 cell. Right. Which gives positive value of E0 cell. Okay. Positive value means what? The potential or reduction potential of A or B. Right. It should be lesser than, lesser than the value of ion. Okay. The given value of ion. That is what we have to find out. Okay. Magnitude we are talking about. See for ion it is 0. Minus 0.44 it is given. Right. For ion, it is minus 0.44. For A it is minus 2.37. So if we find out by this formula, which we have E0 cell is equals to, is equals to E0 of A2 plus 2A conversion minus E0 of Fe2 plus 2Fe. Which is nothing but minus 2.37 minus, minus of 0.44. The value we get here is minus 1.93, 97. 93. Correct. 93 volt we get here. Okay. Now similarly if you find this is for with A. Now if you find out with B E0 cell with B. So for B it is 0.14 plus 0.44. You see this value is 0.30 which is a positive value and that is why we require. So B will be the, is the better coating, is the better for coating on the surface of ion. Okay. See what happens if you take this B and this ion. E0 of the cell is positive and what it means when E0 of the cell is positive, the reduction potential you see Fe2 plus 2Fe and B2 plus 2B both are reduction potential. So reduction potential of this metal whatever it is B is lesser than to that of ion. Right. So when you couple this ion with this B, ion will go under reduction and this will go under oxidation. Right. So that is what it requires for the, you know, for better coating, so for better coating that is what it's required. Hence the answer will be B. You must, one thing you must keep in mind that E0 cell for better coating must be positive. That is what you have to keep in mind. See both has negative potential only. Point is we have to compare A with ion and then B with ion. Then what happens? Both you can use as a coating for the coating of the surface of ion, but which one of these two is better, which gives you positive E0 cell value. Okay. One more question we'll see series reaction I want to to give you this question and then we'll take a break after this question number 24. Yeah. Okay. We solve the first part here. This or part we'll discuss after the break. Solve this part first. This part. What does this H2PDBSO4 does? What does this S2PDBSO4 do? Tell me. Yeah. Yeah, correct. So first one is CS3CHO. Then what happens? What happened with NH2OH? What is this CS3CHNOH? This is oxym formation, right? Formation of oxym. C double bond NOH is oxym. Yes. Yes. Correct. We have done this in the class also. Mechanism we also have seen that we have a rearrangement in this. Right. So first product will be CS3CHO will get aldehyde with equal number of carbon atom. And then the reaction with NH2OH gives you the formation of oxym, which is nothing but C double bond NOH. And H2O will go out into this. Second reaction you tell me. RMGX reacts with CO2 in presence of acetic hydrolysis. Correct. Then with PCL5, COOCl or COCl, C2H5, Cym-L. How did you get C2H5, Cym-L? It should be CS3 COCl. Correct. Okay. Next one you do. Distinguish between all these. C6H5COCH3, C6H5CHO. Which one is tolerance test? This can be distinguished by hydroform test also. Right. Methyl ketone, ketone gives positive hydroform test. C6H5COCH3, that is acetofinone and it is the methyl ketone also. The compound which contains CH3CO group shows positive hydroform test. Right. Which gives yellow precipitate of hydroform with sodium hypoiodide. Right. So what happens? The C6H5COCH3, which is acetofinone gives positive hydroform test but benzaldehyde does not give this test. Right. So hydroform test we can use. Next one is CS3COH, acetic acid and formic acid. What happens here? You see, the formic acid easily decolorize pink color of KMNO4. Write down this. Formic acid easily decolorize pink color of KMNO4 while acetic acid does not again perform this test. Right. Formic acid decolorize pink color of KMNO4. Acetic acid will not do the same. Right. Third one is the boiling point. What is the order of boiling point? Acid, alcohol, aldehyde. Correct. Acid will have the highest boiling, highest boiling point, maximum boiling point and then we have alcohol and then we have aldehyde. Vaishnavi and all of you, you take care of one thing. Last class also I told you this thing. What is the question you see? Arrange the following in increasing order of their boiling point but you have written it in decreasing order. Understood. All of you, Vaishnavi, Saimee, Rithvik, Mrs. Strahm, Ramcharan. If the question given in increasing order, you have to write down in increasing order. It is the decreasing order you have written. Correct. Do take care of all these things. Okay. You know all the things but if you write down like this, you won't get marks, unit and all, everything. Okay. Cool. So we'll take a break. We'll start in 15 minutes. Fine. Right. Can we take a break now about the distinguish between C.V. and M.N. I think you can use bromine water. Yeah. You can use bromine water. Okay. We'll discuss this after the break. We'll discuss this. Correct. Yeah. Bromine water I think you can use. Okay. We'll take a break now. We'll start the class at 5.55. Okay, guys. Can we start? Are you there? Okay. Now solve the second part. Wolf-Krishna reduction, you know. What happened in Wolf-Krishna reduction? C double bond O converts into what? Okay. Tell me the reagent. What reagent we use in Wolf-Krishna reduction? Yes. So C double bond O, hydrazine, NH2, NH2 we use. And C double bond O converts into CH2. Right. So carbonyl compound converts into alkane. So any of these reactions you can write down. Okay. So any carbonyl compound if I write, R C double bond O. R. And when this is heated with hydrazine, NH2, NH2, C2H5O1 or KOH also you can write down. When you heat this, it converts into R CH2R. So basically in this reaction, C double bond O carbonyl group converts into CH2. And other things will be same. This is Wolf-Krishna reduction. Okay. Now arrange the following in increasing order of their reactivity towards nucleophilic addition reaction. Which one is maximum? Suppose I'll write down this as first, then second, and then third. Take care of this thing. Increasing order we have to write. Okay. Increasing order. What is order? See this order depends on two factor. Right. If you have the carbonyl group, C double bond O. So we know this bond, carbon oxygen bond is polar. This is slightly negative charge and this will have slightly positive charge. Where the nucleophile attacks. I didn't get any response stress. I can see your message. I gave my response or you said, but I didn't get any response. Anyways, I'm doing this. So the attack of nucleophile depends on two factor here. One is the steric crowding here. One is this positive charge density. More charge density, more will the attack of nucleophile. More crowding, less will be the attack of nucleophile. Correct. So you see the three compounds we have here. CH3, C double bond O, CH3. Then we have CH3, C double bond OH. And the last one we have PHC double bond O, CH3. In all these example you see, because of the plus high nature of these two group, this positive charge density will be less over here in comparison to this. Right. So if it is this one is two, this one is three, and this one is one. So obviously, second one is more reactive than the third one. Second one is more reactive than the third one. Now here what happens, we have plus high nature of this. Phenyl has electron withdrawing nature. But at the same time what happens, this produces steric crowding also because of large size. So because of steric crowding, the attack of nucleophile will be lesser than these two, two and three. So the order will be this. First, third and two will be maximum. Okay. Tell me the next one. Why carboxylic acid does not give reactions of carbonyl group. See in this carbonyl group we have either C double bond O or C double bond OR or H we can have here. Right. But in carboxylic acid we have RC double bond O OH. So this lone pair is involving resonance in carboxylic acid. Right. So the carbon is not that much electron deficient here. If this bond will come over here, this lone pair will come here and we'll get again a double bond here. So this carbon atom or carbonyl carbon is not that much electron deficient as it is there in aldehyde or ketone. That's why the reaction of carbonyl compound is not given by carboxylic acid generally. Last question you tell me. Write the product in the following reaction. A is propanol B is acetone. Yeah, it's correct. Right. It's a direct reaction to functional isomer. Okay. You can easily find out degree of unsaturation and then you will have the idea that we'll have either one double bond or one ring. Right. And then the direct reaction with NaOH and I2. Okay. Next question we'll see. An element crystallizes in a BCC lattice with cell edge of this density is this. How many atoms are present? Done. What is the answer? Tell me.


Now we're going to talk about a few more things you can do in Word with Zotero. If you select the Zotero tab on top, this is where we did the adding and editing citations and the add or edit bibliography, but there are three other things that we can do. First is document preferences. When I select this, I can change my citation style. Right now I'm on APA, which is author last name and date. But if I select MLA and hit OK, you can see now it's just the last name. I added one more citation so I can show you what the refresh button does. Let's say you wrote your project, but at some point you went back into Zotero and made a change. For example, this mammoth article isn't titled correctly, so if I go in there and make the changes and then go back to my Word document, it's still incorrect. But I can hit refresh from the Zotero tab and it will update that information. Finally, there's unlink citations. If you select unlink citations, all of the information that you brought in from Zotero will just be converted into regular old text. You won't be able to refresh and you won't be able to change citation style with just a few clicks. So be careful about that one because you cannot undo it. And those are all the things you can do in Word with Zotero.
