Vedclass · Answer

(C) $1$. The reaction begins with propene $(C_3H_6)$.$2$. The reagent $X$ is $HBr/ROOR$ (peroxide effect/anti-Markovnikov addition),which converts propene to $1$-bromopropane $(Y = CH_3CH_2CH_2Br)$.$3$. In the presence of $AlCl_3$,$1$-bromopropane undergoes rearrangement to form a more stable isopropyl carbocation $(CH_3CH^+CH_3)$.$4$. This isopropyl carbocation then undergoes Friedel-Crafts alkylation with benzene $(C_6H_6)$ to form isopropylbenzene (cumene) as the major product $(Z)$.$5$. Thus,$X$ is $HBr/ROOR$ and $Z$ is isopropylbenzene.
