(B) The reaction of a Grignard reagent $(RMgX)$ with a nitrile $(R'CN)$ followed by hydrolysis yields a ketone. Specifically,for ethanenitrile $(CH_3CN)$: $CH_3-C \equiv N + RMgX \to CH_3-C(R)=N-MgX$ Upon hydrolysis $(H_2O)$: $CH_3-C(R)=N-MgX + H_2O \to CH_3-C(=O)-R + NH_3 + Mg(OH)X$ Thus,ethanenitrile reacts with a Grignard reagent to form a ketone.
