What happens when anisole is treated with CH3Cl/ anhydrous AlCl3 ? Write a chemical equation in support of your answer.

When anisole is treated with CH3Cl (methyl chloride) in the presence of anhydrous aluminum chloride (AlCl3), it undergoes Friedel-Crafts alkylation to form ortho- and para-methyl anisole. Here's the chemical equation for the reaction:

This reaction is a type of electrophilic aromatic substitution reaction, where the methyl chloride acts as the electrophile, and anhydrous aluminum chloride acts as a Lewis acid catalyst to facilitate the reaction.
