Vedclass · Answer

(C) Friedel-Crafts alkylation involves the reaction of an aromatic ring with an alkyl halide in the presence of a Lewis acid catalyst like $AlCl_3$. $A$: This is a standard methylation of benzene,which is correct. $B$: The reaction of benzene with $n$-propyl chloride $(CH_3CH_2CH_2Cl)$ undergoes rearrangement of the propyl carbocation to a more stable isopropyl carbocation,leading to the formation of isopropylbenzene. This is correct. $C$: Vinyl halides $(CH_2=CHCl)$ do not undergo Friedel-Crafts alkylation because the $C-Cl$ bond has partial double bond character due to resonance,making it very difficult to form the vinyl carbocation. Therefore,this reaction is incorrectly written. $D$: The reaction of benzene with isobutyl chloride $(CH_3CH(CH_3)CH_2Cl)$ involves the rearrangement of the primary carbocation to a more stable tertiary carbocation,resulting in the formation of tert-butylbenzene. This is correct.
