Quizplus · Accepted Answer

In the first step, bromination of benzene takes place in the presence of FeBr3 as a Lewis acid catalyst which results in the formation of bromobenzene. In the second step, bromobenzene undergoes a reaction with magnesium in the presence of dry ether as a solvent which results in the formation of phenylmagnesium bromide. In the third step, phenylmagnesium bromide reacts with formaldehyde in the presence of aqueous acid which results in the formation of benzoic acid. Therefore, the final product is III.
