7.4 Aldehydes & Ketones

Aldehydes are named by replacing the "-ic" or "-oic" of the acid name by "aldehyde".

Examples:


benzaldehyde


o-nitrobenzaldehyde


p-hydroxybenzaldehyde


0-tolualdehyde


salicyaldehyde



Aromatic ketones are named by changing the "-ic" or "-oic" ending of the acid name corresponding to the acyl group attached to the benzene ring to "-ophenone".

Examples:


acetophenone


propiophenone


m-nitrobutyrophenone



Aldehydes and ketones in which the carbonyl group is not directly attached to the aromatic ring are named using the corresponding group name for the aromatic system as a prefix.

Examples:


phenylacetaldehyde


1-(m-nitrophenyl)-2-butanone
