NEET levelSingle correct optionDifficulty 1 of 3nc187

Aniline reacts with acetic anhydride in the presence of pyridine to give

Aacetanilide
Bacetophenone
CN-methylaniline
Dbenzanilide

Answer: A

Acylation replaces an N-H hydrogen by the acetyl group

CH X_{3} CO X^{-}

, so

C X_{6} H X_{5} NH X_{2}

gives

C X_{6} H X_{5} NHCOCH X_{3}

, acetanilide. Benzanilide would need benzoyl chloride.
