A functional group composed of a carbon atom double-bonded to an oxygen atom: C=O.
For carbonyl as a ligand, see Metal carbonyl. A compound containing a carbonyl group (C=O). In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O. It is common to several classes of organic compounds, as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carbonyl compound. 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 following resonance structures. Carbonyl and carboxyl are common functional groups found in organic chemistry. Both have an oxygen atom, which is double bonded to a carbon atom. Carbonyl. Carbonyl group is a functional group with double bonded oxygen to a carbon. Aldehydes and ketones are known as organic molecules with a carbonyl group. The carbonyl group in an aldehyde always gets number one in the nomenclature as it is located at an end of the carbon chain. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde. Definition: the term carbonyl refers to the carbonyl functional group which is a divalent group consisting of a carbon atom with a double-bond to oxygen. Carbonyl also may refer to a compound formed by a metal with carbon monoxide.
