Vedclass · Answer

(D) The reaction sequence is as follows:$1$. Toluene reacts with $Br_2$ in the presence of light (free radical substitution) to form benzyl bromide $(C_6H_5CH_2Br)$ as product $(A)$.$2$. Benzyl bromide reacts with $KCN$ (nucleophilic substitution) to form benzyl cyanide $(C_6H_5CH_2CN)$.$3$. Acidic hydrolysis of benzyl cyanide $(H_3O^+)$ yields phenylacetic acid $(C_6H_5CH_2COOH)$ as the final product $(B)$.

What is the final product $(B)$ of this sequence?
