In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double bonded to an oxygen atom C O.

If the acid is a carboxylic acid, the compound contains a COX functional group, which consists of a carbonyl group singly bonded to a halogen atom.

Carbonyl fluoride is the inorganic compound with the formula COF2.

The general formula for such an acyl halide can be written RCOX, where R may be, for example, an alkyl group, CO is the carbonyl group, and X represents the halide, such as chloride.

It is an extensively conjugated system, as the lone pair on the hydroxyl oxygen, the benzene pi cloud, the nitrogen lone pair, the p orbital on the carbonyl carbon, and the lone pair on the carbonyl oxygen are all conjugated.

When an α hydrogen is present (as is the case when the carbonyl is an aldehyde), it will tautomerize to the corresponding enone.

The proposed reaction mechanism involves an attack of an enzyme nucleophile on the carbonyl carbon (Cγ) of the tautomerized 3hKyn PLP Schiff base.

Other compounds detected in volcanic gases are oxygen (meteoric), hydrogen chloride, hydrogen fluoride, hydrogen bromide, nitrogen oxide (NOx), sulfur hexafluoride, carbonyl sulfide, and organic compounds.
