$CH_3MgBr + CH_3-CN \xrightarrow{H_3O^{+}}$

Vedclass · Answer

(C) In reaction $(c)$,a Grignard reagent reacts with a nitrile to form an imine salt,which upon hydrolysis yields a ketone: $CH_3MgBr + CH_3-CN$ $\rightarrow CH_3-C(CH_3)=NMgBr$ $\xrightarrow{H_3O^{+}} CH_3-CO-CH_3$ (Acetone). The other reactions are: $(a)$ Catalytic reduction of nitrile to imine followed by hydrolysis gives $CH_3-CHO$. $(b)$ Rosenmund reduction of acid chloride gives $CH_3-CHO$. $(d)$ $DIBAL-H$ reduction of acid chloride gives $CH_3-CHO$.
