Vedclass · Answer

(D) $1$. The reaction of benzonitrile $(C_6H_5CN)$ with a Grignard reagent $(RMgX)$ followed by acid hydrolysis yields a ketone.$2$. The reaction proceeds as follows: $C_6H_5CN + C_6H_5MgBr \rightarrow C_6H_5C(NMgBr)C_6H_5$.$3$. Upon hydrolysis: $C_6H_5C(NMgBr)C_6H_5 + 2H_2O \rightarrow C_6H_5COC_6H_5 + NH_3 + Mg(OH)Br$.$4$. Since the product is benzophenone $(C_6H_5COC_6H_5)$, the Grignard reagent must be phenylmagnesium bromide $(C_6H_5MgBr)$.

Benzonitrile $(C_6H_5CN)$ reacts with a Grignard reagent in dry ether followed by hydrolysis to form benzophenone $(C_6H_5COC_6H_5)$ along with ammonia $(NH_3)$ and hydroxymagnesium bromide $(Mg(OH)Br)$. Identify the reagent used in the above transformation.
