Vedclass · Answer

(B) The reaction of an alkyl nitrile with a Grignard reagent $(PhMgBr)$ followed by acidic hydrolysis $(H_3O^+)$ proceeds as follows:$1$. The nucleophilic phenyl group $(Ph^-)$ from $PhMgBr$ attacks the electrophilic carbon of the nitrile group $(-CN)$ to form an imine salt intermediate.$2$. Upon acidic hydrolysis $(H_3O^+)$, the imine salt is converted into an imine, which is unstable and further hydrolyzes to form a ketone.$3$. The reaction sequence is: $R-CN + PhMgBr$ $\rightarrow R-C(Ph)=N-MgBr$ $\xrightarrow{H_3O^+} R-C(Ph)=NH$ $\xrightarrow{H_3O^+} R-C(=O)Ph$.$4$. In this case, $R$ is an isopropyl group, so the final product is $3$-methyl-$1$-phenylbutan-$1$-one.
