JEE Main levelOne or more correct optionsDifficulty 2 of 3o1197

Which statements about N-methylacetamide are correct?

Aheating with aq. NaOH gives sodium acetate and methanamine
Bthe C-N bond has partial double-bond character
Cit is hydrolysed faster than ethyl acetate under the same conditions
Dheating with aq. HCl gives acetic acid and methylammonium chloride

Answer: A, B, D

Base hydrolysis gives

CH X_{3} COO X^{-}

and

CH X_{3} NH X_{2}

; acid hydrolysis gives

CH X_{3} COOH

and

CH X_{3} NH X_{3} X^{+}

. The C-N partial double bond comes from nitrogen lone-pair delocalisation, which also makes amides much less reactive than esters.
