- Any functional group that has these can hydrogen-bond with neighboring molecules: 1  C=O (hydrogen-bond acceptor) 2  C−O−C (hydrogen-bond acceptor) [some] 3  C−NR (hydrogen-bond acceptor) 4  C=NR (hydrogen-bond acceptor) 5  C−OH (hydrogen-bond donor AND acceptor) 6  C−NH (hydrogen-bond donor AND acceptor) 7  C=NH (hydrogen-bond acceptor AND donor)

- The carbonyl group is a super function because many common functional groups are based on a carbonyl, including: aldehydes, ketones, carboxylic acids, esters, amides, acyl (acid) chlorides, acid anhydrides. aldehydes, ketones, carboxylic acids, esters, amides, acyl (acid) chlorides, acid anhydrides.arboxylic acids have an alkyl or aromatic groups attached to a hydroxy-carbonyl function. Carboxylic acids can be shown in text as: RCOOH Carboxylic acids are weak Bronsted acids and they liberate CO2 from carbonates and hydrogen carbonates.

- In organic chemistry, functional groups are specific groups (moieties) of atoms or bonds within molecules that are responsible for the characteristic chemical reactions of those molecules.n contrast, unsaturated carbon functional groups, and carbon-oxygen and carbon-nitrogen functional groups have a more diverse array of reactions that are also selective. It may be necessary to create a functional group in the molecule to make it react.

- The group of atoms that is largely responsible for the chemical behavior of a molecule is called a functional group. For instance, alcohols contain an alkane group and a hydroxyl group, OH. Methanol (CH3OH), ethanol (C2H5OH), and n-propanol (C3H7OH) are the first three alcohols of a homologous series. In each of the three, chemical reactions occur at the OH group, rather than at the less reactive alkane group.

- Functional groups focus attention on the important aspects of the structure of a molecule. We don't have to worry about the differences between the structures of 1-butene and 2-methyl-2-hexene, for example, when these compounds react with hydrogen bromide.

Structural Biochemistry/Chemical Bonding/Hydrogen bonds A hydrogen bond is formed by a dipole-dipole force between an electronegative atom (the hydrogen acceptor) and a hydrogen atom that attaches covalently with another electronegative atom (the hydrogen donor) of the same molecule or of a different molecule. hydrogen-bond donor includes the hydrogen atom and the atom to which it is most tightly linked with. The hydrogen-bond also play a very important roles in proteins' structure because it stabulizes the secondary, tertiary and quaternary structure of proteins which formed by alpha helix, beta sheets, turns and loops.

Hydrogen bonds are formed between molecules when hydrogen is covalently bonded to an element that has a ? An electronegative atom such as fluorine, oxygen, or nitrogen will be the hydrogen bond acceptor, whether or not it is bonded to a hydrogen atom. An example of a hydrogen bond acceptor that does not have a hydrogen atom bonded to it is the oxygen atom in diethyl ether.

Common Functional Groups - Organic Chemistry Functional groups are collections of atoms in organic chemistry molecules that contribute to the chemical characteristics of the molecule and participate in predictable reactions. These groups of atoms contain oxygen or nitrogen or sometimes sulfur attached to a hydrocarbon skeleton.. Also known as the carboxyl functional group. The carboxyl group is an ester where one substituent R is a hydrogen atom. The carboxyl group is usually denoted by-COOH. This is the general structure of the thiol functional group.

- Key concepts: A hydrogen bond is formed by the interaction of a hydrogen atom that is covalently bonded to an electronegative atom (donor) with another electronegative atom (acceptor). Hydrogen bonding confers rigidity to the protein structure and specificity to intermolecular interactions.

- An electronegative atom such as fluorine, oxygen, or nitrogen will be the hydrogen bond acceptor, whether or not it is bonded to a hydrogen atom. An example of a hydrogen bond acceptor that does not have a hydrogen atom bonded to it is the oxygen atom in diethyl ether.he hydrogen bond (5 to 30 kJ/mole) is stronger than a van der Waals interaction, but weaker than covalent or ionic bonds. This type of bond can occur in inorganic molecules such as water and in organic molecules like DNA and proteins.

Functional Groups and Hydrogen Bonding? Best Answer: Hydrogen bonds are only possible for atoms containing hydrogen bonded to oxygen, nitrogen or fluorine. So in the above methyl, phosphate and sulhydryl can't form hydrogen bonds since their hydrogens are bonded to carbon, phosphorus or sulfur.

Common Functional Groups in Organic Chemistry in Organic Chemistry. Saturated hydrocarbon chains (such as simple alkanes) are relatively unreactive. The reactions and reactivity of organic compounds are often determined by the functional groups attached to the carbon chain of which they are a part.

Hydrogen Bond Examples Hydroflouric and formic acids have a special type of hydrogen bond called a symmetric hydrogen bond. This bond is much stronger than a regular hydrogen bond, and can be seen in these acids when they are kept at a high pressure. Hydrogen bonds between proteins result in a phenomenon known as protein folding.

- Each functional group differs from the other by the type of bonds or by the type of hetroatoms they contain. The most common functional groups are known as alkanes, alkenes, alkynes, aromatic hydrocarbons, organic halides, alcohols, aldehydes, ketones, esters, carboxylic acids, amines and amides.

Structural Biochemistry/Chemical Bonding/Hydrogen bonds This partial positive charge is attracted to the partial negative charge of the hydrogen bond acceptor (an electron density rich atom). The chemical bond formed between the hydrogen-bond donor, hydrogen atom, and hydrogen-bond acceptor has a straight, linear structure. hydrogen-bond donor includes the hydrogen atom and the atom to which it is most tightly linked with. The hydrogen-bond also play a very important roles in proteins' structure because it stabulizes the secondary, tertiary and quaternary structure of proteins which formed by alpha helix, beta sheets, turns and loops.

Functional group Functional groups, called hydrocarbyl, that contain only carbon and hydrogen, but vary in the number and order of double bonds. Each one differs in type (and scope) of reactivity. There are also a large number of branched or ring alkanes that have specific names, e.g., tert-butyl, bornyl, cyclohexyl, etc.

What are hydrogen bonds? Confidence votes 172. Hydrogen bonds are the bonds that are formed due interaction of a hydrogen atom with an electronegative atom (like oxygen). In these interactions, a hydrogen atom (consisted of only one proton and one electron) is a donor, and the respective electronegative atom is an acceptor of the bond.

The Concept of Functional Groups Thus the chemical formula for an aldehyde functional group is-CH=O, and the general formula for an aldehyde is R-CH=O. The aldehyde group is occasionally called the formyl or methanoyl group. Other classes of organic compounds containing carbonyl groups include ketones and carboxylic acids. wikipedia.ccording to a general definition of Aldehyde that says: An aldehyde is an organic compound containing a terminal carbonyl group. This functional group, called an aldehyde group, consists of a carbon atom bonded to a hydrogen atom with a single covalent bond and an oxygen atom with a double bond.

- Because of this small difference in electronegativities, the C−H bond is generally regarded as being non-polar. In structural formulas of molecules, the hydrogen atoms are often omitted. Compound classes consisting solely of C–H bonds and C–C bonds are alkanes, alkenes, alkynes, and aromatic hydrocarbons.

Organic Chemistry/Overview of Functional Groups Functional groups are specific atoms, ions, or groups of atoms having consistent properties. A functional group makes up part of a larger molecule. For example, -OH, the hydroxyl group that characterizes alcohols, is an oxygen with a hydrogen attached. It could be found on any number of different molecules.Just as elements have distinctive properties, functional groups have characteristic chemistries.or example, -OH, the hydroxyl group that characterizes alcohols, is an oxygen with a hydrogen attached.
