Vedclass · Answer

(D) The reaction of $R-C \equiv N$ with $H_3O^+$ (acidic hydrolysis) typically requires heating to proceed to the carboxylic acid stage. Under mild conditions,it often stops at the amide stage $(R-CONH_2)$. Thus,statement $(A)$ is generally considered incorrect as it implies a simple,mild reaction.When alkyl cyanide $(R-C \equiv N)$ is hydrolysed in an alkaline aqueous medium,it undergoes hydrolysis to form a carboxylate salt $(R-COO^-Na^+)$ and ammonia $(NH_3)$. Thus,statement $(B)$ is correct.

Statement $(A)$: Carboxylic acid can be obtained by the reaction of $R-C \equiv N$ with $H_3O^+$ under mild reaction conditions.
Statement $(B)$: Hydrolysis of $R-C \equiv N$ in alkaline aqueous medium gives $R-COONa$ and $NH_3$ as products.
The correct answer is:
