Vedclass · Answer

(D) In the Friedel-Crafts reaction,$AlCl_3$ acts as a Lewis acid catalyst.It reacts with the alkyl halide or acyl halide to generate a carbocation or an acylium ion,which acts as an electrophile.This electrophile then attacks the benzene ring to initiate the substitution reaction.For example: $CH_3-CH_2-CH_2-Cl + AlCl_3 \rightarrow CH_3-CH_2-CH_2^+ + AlCl_4^-$.
