Carbonyl 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, C=O. Carbonyl also may refer to a compound formed by a metal with carbon monoxide (=CO). Bivalent radical CO is found in ketones, acids, and aldehydes. Many of the molecules involved in the senses of smell and taste involve aromatic compounds with carbonyl groups.

The C=O entity is the carbonyl group, while a molecule that contains the group is called a carbonyl compound.

Also Known As: carbonyl group, carbonyl functional group

Carbonyl Example

The metal compound nickel carbonate, Ni(CO)4, contains the CO carbonyl group.
