The refluxing of \[{{\text{(C}{{\text{H}}_{\text{3}}}\text{)}}_{\text{2}}}\text{NCOC}{{\text{H}}_{\text{3}}}\]with acid gives:

A)  \[{{\text{(C}{{\text{H}}_{3}}\text{)}}_{2}}NH+C{{H}_{3}}COOH\]

B)  \[{{(C{{H}_{3}})}_{2}}NCOOH+C{{H}_{4}}\]

C)  \[2C{{H}_{3}}OH+C{{H}_{3}}CON{{H}_{2}}\]

D)  \[2C{{H}_{3}}N{{H}_{2}}+C{{H}_{3}}COOH\]

Correct Answer: A

Solution :

Amides on acidic hydrolysis, give acid and an amine. Hence, N-dimethyl acetamide will give acetic acid and dimethyl amine on hydrolysis.
