Description of the Carbonyl Group ... It is somewhat misleading to write the carbonyl group as a covalent C=O double bond. The difference between the electronegativities of carbon and oxygen is large enough to make the C=O bond moderately polar. As a result, the carbonyl group is best described as a hybrid of the...

Carboxylic acids are organic acids characterized by the presence of a carboxyl group, which has the formula -C(=O)OH, usually written -COOH or -CO 2 H. Carboxylic acids are Brønsted-Lowry acids — t...

Since an aldehyde carbonyl group must always lie at the end of a carbon chain, it is by default position #1, and therefore defines the numbering direction. A ketone carbonyl function may be located anywhere within a chain or ring, and its position is given by a locator number.

Re: What is a carbonyl group? Area: Chemistry ; Posted By: Dan Berger, Faculty Chemistry/Science, Bluffton College; Date: Fri Feb 7 13:21:06 1997 ... A carbonyl group is a carbon-oxygen double bond. Oxygen can have only two bonds, so nothing else can be bonded to oxygen, but carbon forms four bonds, so there are two...

A carbonyl group is a group of atoms that consists of a carbon atom covalently attached to an oxygen atom by a double bond: C = O. The carbon atom, to satisfy its valence of 4, must also be attached by covalent bonds to two other atoms.

The carbonyl group ... Where the carbon-oxygen double bond, C=O, occurs in organic compounds it is called a carbonyl group. The simplest compound containing this group is methanal. ... Note: Methanal is normally written as HCHO. If you wrote it as HCOH, it looks as if it contains an -O-H group - and it doesn't.
