What purpose does FeCl3 serve in the electrophilic aromatic substitution
reaction between chlorine and benzene?
(a) It serves as a radical initiator to produce the chlorine radical needed to
propagate the chain reaction.
(b) It functions by destabilizing the carbocationic intermediate and thereby
increases the rate of H+ loss.
(c) It serves as a Lewis base catalyst by reacting with Cl2 to generate chloride
ions.
(d) It serves as a Lewis acid catalyst by reacting with the Cl2 and thereby activates
it toward attack by benzene’s π electrons.
