Benzophenone

Vedclass · Answer

(A) The reaction of benzonitrile $(C_6H_5CN)$ with phenylmagnesium bromide $(C_6H_5MgBr)$ in the presence of dry ether forms an intermediate imine salt $(A)$: $C_6H_5-C(C_6H_5)=NMgBr$.Upon acid hydrolysis $(H_3O^{+})$,this intermediate is converted into a ketone,specifically benzophenone $(C_6H_5-CO-C_6H_5)$,along with ammonia $(NH_3)$ and magnesium hydroxybromide $(Mg(Br)OH)$.Therefore,product $B$ is benzophenone.

Identify product $B$ in the following reaction:
Benzonitrile $\xrightarrow[\text{Dry ether}]{C_6H_5MgBr} A$ $\xrightarrow{H_3O^{+}} B$
