Vedclass · Answer

(C) Friedel-Crafts alkylation is an electrophilic aromatic substitution reaction. It does not occur with strongly deactivated rings (like benzoic acid,which has a $-COOH$ group) or with compounds that form a complex with the Lewis acid catalyst (like aniline,which has a $-NH_2$ group that coordinates with $AlCl_3$). Chlorobenzene is deactivated due to the $-I$ effect of the chlorine atom,making it very slow to react,but it is generally considered to undergo the reaction under specific conditions. Anisole (methoxybenzene) is an activated ring due to the $+M$ effect of the $-OCH_3$ group and readily undergoes Friedel-Crafts alkylation. Therefore,$b$ (Chlorobenzene) and $d$ (Anisole) are the compounds that can undergo this reaction.

Which of the following will undergo Friedel-Crafts alkylation with $CH_3Cl$ / anhy. $AlCl_3$?
