Question

What purpose does FeCl3 serve in the electrophilic
aromatic substitution reaction between chlorine and
benzene?
It serves as a radical initiator to produce the
chlorine radical needed to propagate the chain
reaction
It functions by destabilizing the carbocationic
intermediate and thereby increases the rate of
H+ loss​

Answer 1

Answer:

It serves as a radical initiator to produce the chlorine radical needed to propagate the chain reaction. It functions by destabilizing the carbocation intermediate and thereby increases the rate of H+ loss. It serves as a Lewis base catalyst by reacting with Cl2 to generate chloride ions. It functions by destabilizing the benzene through formation of a Ti-complex. It serves as a Lewis acid catalyst by reacting with the Cl2 and thereby activates it toward attack by benzene's pi electrons.
