Vedclass · Answer

(A) $1$. Friedel-Crafts acylation of benzene with acetic anhydride $(CH_3CO)_2O$ in the presence of $AlCl_3$ gives acetophenone $(X = C_6H_5COCH_3)$.$2$. Clemmensen reduction of acetophenone $(X)$ using $Zn-Hg, HCl$ reduces the carbonyl group to a methylene group,yielding ethylbenzene $(Y = C_6H_5CH_2CH_3)$.$3$. Reaction of ethylbenzene $(Y)$ with $N$-bromosuccinimide $(NBS)$ is a radical substitution reaction that occurs at the benzylic position,yielding $1-$bromo$-1-$phenylethane $(Z = C_6H_5CH(Br)CH_3)$.

Benzene $+ (CH_3CO)_2O$ $\xrightarrow{AlCl_3} X$ $\xrightarrow{Zn-Hg, HCl} Y$ $\xrightarrow{NBS} Z$;
$Z$ is
