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.

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

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 .

Try out the following:

1. 2-methylhexa-2,4-dienediamide
2. hexane-1,3,6-tricarboxamide
3. 5-(2-amino-2-oxoethyl)heptane-1,3,7-tricarboxamide
4. 5-(3-amino-3-oxopropyl)hept-5-en-3-yne-1,2,6-tricarboxamide
5. 5,6-bis(2-amino-2-oxoethyl)decanediamide
