A '''carbonyl group''' is a [[functional group]] which consists of a [[carbon]] atom with is double bound to an [[oxygen]] atom. Closely related chemical groups include [[carboxylic acid]]s, in which R<sub>1</sub> or R<sub>2</sub> = OH, [[ester]]s, in which R<sub>1</sub> or R<sub>2</sub> = OR, and [[amide]]s, in which R<sub>1</sub> or R<sub>2</sub> = N(R<sub>3</sub>)R<sub>4</sub>.  The chemical weapon [[phosgene]] is a carbonyl group with R<sub>1</sub>=R<sub>2</sub>=Cl.
 
 
Carbonyl groups are polar and the carbon atom is [[electrophile|electrophilic]]. As such, [[nucleophilic attack]] of the carbon atom is a useful reaction mechanism for chemicals containing a carbonyl group.

A carbonyl group is a functional group which consists of a carbon atom with is double bound to an oxygen atom. Closely related chemical groups include carboxylic acids, in which R1 or R2 = OH, esters, in which R1 or R2 = OR, and amides, in which R1 or R2 = N(R3)R4. The chemical weapon phosgene is a carbonyl group with R1=R2=Cl.


Carbonyl groups are polar and the carbon atom is electrophilic. As such, nucleophilic attack of the carbon atom is a useful reaction mechanism for chemicals containing a carbonyl group.
