Nomenclature of Acid Amide

Acid amides are the derivatives of carboxylic acids with –CONH2 as the functional group.

Rules

1.The numbering of the carbon chain starts from the carbon of –CONH2 group. For naming it, alkane-e+amide.

pentanamide

2.If two –CONH2 groups are present, they will be treated as the terminal carbons irrespective of the carbon chain. It is named as: Alkanediamide

hexanediamide
pentylhexanediamide

3. If three –CONH2 groups are present, the stem chain holding –CONH2 groups directly will be taken as the main chain, and the –CONH2 groups will be known as tricarboxamide. The compound is named as: alkane-x,y,z-tricarboxamide.

4. If one of the –CONH2 groups is not directly connected. Then the longest chain holding two terminal –CONH2 groups will the treated as the parental chain and the third one will be named as: amino oxo alkyl .
