Vedclass · Answer

(C) Let us analyze each reaction:$(A)$ Acidic hydrolysis of benzonitrile $(C_6H_5CN)$ yields benzoic acid $(C_6H_5COOH)$. This is correct.$(B)$ Controlled reduction of nitriles with $DIBAL-H$ followed by hydrolysis yields aldehydes $(C_6H_5CHO)$. This is correct.$(C)$ Reduction of nitriles with $LiAlH_4$ followed by hydrolysis yields primary amines $(C_6H_5CH_2NH_2)$,not primary alcohols $(C_6H_5CH_2OH)$. This is incorrect.$(D)$ Reaction of nitriles with Grignard reagents $(PhMgBr)$ followed by hydrolysis yields ketones $(C_6H_5COC_6H_5)$. This is correct.Therefore,the incorrect reaction is $(C)$.
