Question

What steps are used to name secondary and tertiary amides?

Answer 1

Mono- and disubstituted amides are named as N-alkylakanamides or
N,N-dialkylalkanamides.

You name an amide by dropping the -oic acid ending of the parent acid and adding -amide. Substituents on the N atom are located by the locant N-, which is listed first.

Examples

CH₃CH₂CH₂CONHCH₃ is N-methylbutanamide .

CH₃CON(CH₃)₂ is N,N-dimethylethanamide.

CH₃CH(CH₃)CON(CH₃)CH₂CH₃ is N-ethyl-N,2-dimethylpropanamide.

Note: Every substituent must have a locant. The name is all one word (no spaces).
