If the Assertion is correct but Reason is incorrect.

Vedclass · Answer

(C) The assertion is correct: Acylation of amines (using acid chlorides or anhydrides) results in a monosubstituted product because the electron-withdrawing nature of the acyl group reduces the nucleophilicity of the nitrogen atom,preventing further acylation. In contrast,alkylation of amines (using alkyl halides) leads to a mixture of primary,secondary,tertiary amines,and quaternary ammonium salts because the alkyl group is electron-donating,which increases the nucleophilicity of the nitrogen atom,making it more reactive toward further alkylation. The reason is incorrect: The limitation of acylation is due to the electronic effect (electron-withdrawing nature of the acyl group) rather than steric hindrance. Therefore,the assertion is correct,but the reason is incorrect.

Assertion : Acylation of amines gives a monosubstituted product whereas alkylation of amines gives polysubstituted product.
Reason : Acyl group sterically hinders the approach of further acyl groups.
