Vedclass · Answer

(A) The reaction of benzene $(C_6H_6)$ with ethene $(H_2C = CH_2)$ in the presence of an anhydrous $AlCl_3$ catalyst (often with a trace of $HCl$) is an example of Friedel-Crafts alkylation.This reaction proceeds via the formation of an ethyl carbocation intermediate,which then attacks the benzene ring to form ethylbenzene $(C_6H_5CH_2CH_3)$.The reaction is: $C_6H_6 + H_2C = CH_2 \xrightarrow{AlCl_3, HCl} C_6H_5CH_2CH_3$.

Using anhydrous $AlCl_3$ as a catalyst,which one of the following reactions produces ethylbenzene $(PhEt)$?
