Nomenclature of Carboxylic Acid Derivatives

The table reviews the functional group nomenclature of the carboxylic acid derivatives and shows the simple structural representation and a JSMOL 3D model. It's a good idea to make sure you can recognise each of these functional groups.

Acyl Chlorides
Functional group suffix = oyl chloride (review)
Functional group suffix = alkanoic anhydride (review)
Functional group suffix = alkyl -thioate
Functional group prefix = alkthiocarbonyl-  or   carbalkthio-
Functional group suffix = alkyl -oate (review
Functional group prefix = alkoxycarbonyl-  or   carbalkoxy-
Cyclic esters are called lactones
Carboxylic Acids
Functional group suffix = -oic acid (review
Functional group prefix = carboxy-
Functional group suffix = amide (review
Functional group prefix = carbamoyl-
Cyclic amides are called lactams
Functional group suffix = nitrile or -onitrile (review
Functional group prefix = cyano-
