Question

What is the role of aluminum-based catalysts in Friedel Crafts alkylation?

Accepted Answer

They form carbocations by reacting with alkyl halides, which then attack the benzene ring.

Answer

They act as solvents for the reaction, increasing the rate of alkylation.

Answer

They decompose the benzene ring, making it more reactive.

Answer

They replace a hydrogen on benzene with an alkyl group directly.
