Vedclass · Answer

(D) The reaction of ethylbenzene with bromine in the presence of a Lewis acid catalyst like $FeBr_3$ is an electrophilic aromatic substitution reaction (bromination).The ethyl group $(-CH_2CH_3)$ is an ortho/para-directing group because it is an electron-donating group by inductive effect and hyperconjugation.Therefore,the incoming electrophile $(Br^+)$ will attack the ortho and para positions of the benzene ring.Since the para-isomer is generally more stable due to less steric hindrance compared to the ortho-isomer,the major product formed is $p$-bromoethylbenzene.

Reaction of ethylbenzene with bromine in the presence of $FeBr_3$ yields:
