Why do polar compounds dissolve in water and non-polars compounds don't? Relevance. Rating Newest Oldest. Best Answer: The general rule is like dissolves like, so polar compounds will dissolve in water (which is polar) and non-polar compounds will dissolve in butane (non-polar). The water/butane are just examples-you can replace them with anything that is polar/non-polar, respectively.

- Quick Answer. Substances that have ionic molecules or polar molecules generally dissolve in water because water molecules have the ability to surround the those molecules completely and disperse them in solution. Non-polar molecules do not interact with water molecules and are therefore insoluble in water. Continue Reading

Hydrophile Some hydrophilic substances do not dissolve. This type of mixture is called a colloid. An approximate rule of thumb for hydrophilicity of organic compounds is that solubility of a molecule in water is more than 1 mass % if there is at least one neutral hydrophile group per 5 carbons, or at least one electrically charged hydrophile group per 7 carbons. Hydrophilic substances (ex: salts) can seem to attract water out of the air.

How do you determine if molecules are polar or non-polar? Non-polar molecules do not dissolve in water as they cannot form hydrogen bonds, and so they are hydrophobic. A non-polar molecule is one that the electrons are distributed … more symmetrically. They do not have an abundance of charges at the opposite sides, and the charges cancel out each other.

Structural Biochemistry/Water Water's Solvent Properties. Water, which not only dissolves many compounds but also dissolves more substances than any other liquid, is considered the universal solvent. A polar molecule with partially-positive and negative charges, it readily dissolves ions and polar molecules. Water is therefore referred to as a solvent: a substance capable of dissolving other polar molecules and ionic compounds.

- Polar substances are not likely to dissolve to a significant degree in nonpolar solvents. For example, ionic compounds are insoluble in hexane. It is more difficult to predict the solubility of polar molecular substances than to predict the solubility of ionic compounds and nonpolar molecular substances.Many polar molecular substances are soluble in both water and hexane.ut by trend, ionic and polar solutes are more soluble in polar solvents and non-polar molecules are soluble in non-polar (mostly organic) solvents. The units of concentration we just discussed are used to describe the degree to which a solute is soluble in a solvent.

Introduction Water interacts differently with charged and polar substances than with nonpolar substances because of the polarity of its own molecules. Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. The unequal charge distribution in a water molecule reflects the greater electronegativity, or electron-greediness, of oxygen relative to hydrogen: the shared electrons of the O-H bonds spend more time with the O atom than with the Hs.

- Polar Solute and Solvent. For the solute to dissolve into the solvent, dipole dipole forces are broken which require large amount of energy. However when they do dissolve, the molecules in the solute and solvent are able to form dipole dipole forces which releases large amount of energy.on-polar Solute and Solvent. For the solute to dissolve, the dispersion forces between the molecules in the solute and solvent need to break. This only requires very little energy.

- This means that if a compound is polar, then it can only be dissolved in a polar solvent. Following this logic, a non-polar compound can only be dissolved in a non-polar solvent. In a separatory funnel, there are two phases, the aqueous layer is polar, and the organic layer is non-polar.

- They usually melt at temperatures of about 300-1000°C. (Some ionic compounds or ˝salts ˛ which contain water of crystallization may lose it at temperatures lower than 300°C.)Many ionic compounds dissolve in water because of the strong attractions between the ions andthe highly polar water molecules.

What are the four factors that affect dissolving?? 3. Polarity:The Polarity of the solute and solvent molecules will affect the solubility. Generally polar solute molecules will dissolve in polar solvents and non-polar solute molecules will dissolve in non-polar solvents. The polar solute molecules have a positive and a negative end to the molecule. If the solvent molecule is also polar, then positive ends of solvent molecules will attract negative ends of solute molecules. This is a type of intermolecular force known as dipole-dipole interaction.

Mekong In English the river is called the Mekong River, derived from Mae Nam Khong, a term of both Thai and Lao origin. In the Lao-Thai toponymy, rivers translates to mother of water, signalled by the prefix mae, meaning mother, and nam for water.n the Mekong's case, Mae Nam Khong means Khong, The mother of water. Many Northern Thai and Laos locals refer to it as the River Khong. Such is the case with the Mae Nam Ping in Chiang Mai which is known as the  Ping River .

Qualitative Solubility Predictions? For the first one, SO2 will dissolve well in water as it is polar. The last one, C6H6 is non polar and so will dissolve in carbon tet. For the others, I recommend figuring out the structures.If they have alcohol or carboxylic acid groups or are ionic they will dissolve best in water.Otherwise, carbon tet is the best choice.arbon tetrachloride is a non polar solvent and will only dissolve non polar substances Water however is polar, and so will dissolve polar substances.

- 1 Water can dissolve salt because the positive part of water molecules attracts the negative chloride ions and the negative part of water molecules attracts the positive sodium ions. 2  The amount of a substance that can dissolve in a liquid (at a particular temperature) is called the solubility of the substance.ince water is more polar than alcohol, it attracts the positive sodium and negative chloride ions better than alcohol. This is why water dissolves more salt than alcohol does. Another way of saying this is that the solubility of salt is greater in water than in alcohol.

Replies But 1-hexanol (C6H14O) is only partially soluble in water. Compounds that are less polar, like diethyl ether (C4H10O) aren't soluble at all in water. When two compounds are mutually insoluble they're immiscible with each other: water is not miscible with diethyl ether.So when you mix hydrocarbons with water, they tend to form layers.Water is more dense than more hydrocarbons, so it is usually the bottom layer.The organic (hydrocarbon) layer is usually on top.ecause what is polar and more hydrocarbons are non-polar. The rule rule like dissolves in like.. Hydroxyl (-OH) groups are very polar. But alkyl (-CH3, -CH2CH3 etc.) groups are non-polar.
