question 80

Multiple Choice

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 functions by destabilizing the benzene through formation of a π-complex.
• E)It serves as a Lewis acid catalyst by reacting with the Cl₂ and thereby activates it toward attack by benzene's π electrons.
