Solution

The correct option is A C6H6+CH3Cl

Friedel–Crafts alkylation involves the alkylation of an aromatic ring with an alkyl halide using a strong Lewis acid AlCl3 as the catalyst.With anhydrous aluminium chloride as a catalyst, the alkyl group attaches at the former site of the chloride ion.

Toulene is prepared by keeping -R as CH3 group.

So Toulene is prepared by C6H6+CH3Cl
