Question

What product is formed when benzene is treated with each organic halide in the presence of ${\mathbf{AlCl}}_{\mathbf{3}}$.

Short answer

The reaction that involves the replacement of an aromatic proton (hydrogen atom on the benzene ring) by an alkyl group is named as Friedel-Crafts alkylation reaction.

The reaction proceeds by the generation of an alkyl cation from an alkyl halide.

Step-by-step solution
