Phenylacetic acid

Vedclass · Answer

(D) The reaction sequence is as follows:$1$. Toluene $(Ph-CH_3)$ reacts with $Br_2$ in the presence of light (free radical substitution) to form benzyl bromide $(Ph-CH_2Br)$ as product $(A)$.$2$. Benzyl bromide $(Ph-CH_2Br)$ reacts with $KCN$ (nucleophilic substitution) to form benzyl cyanide $(Ph-CH_2CN)$.$3$. Acidic hydrolysis ($H_3O^{\oplus}$,heat) of benzyl cyanide converts the cyano group $(-CN)$ into a carboxylic acid group $(-CO_2H)$,yielding phenylacetic acid $(Ph-CH_2CO_2H)$ as the final product $(B)$.
