MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Friedel-Crafts alkylation is an electrophilic aromatic substitution reaction in which an alkyl group is introduced into an aromatic ring. The typical reactants are an aromatic compound, such as benzene ( C _6 H _6), and an alkyl halide, such as methyl chloride ( CH _3 Cl ). The reaction is carried out in the presence of a Lewis acid catalyst like anhydrous AlCl _3. C _6 H _6 + CH _3 Cl Anhydrous AlCl _3 C _6 H _5 CH _3 + HCl The reaction of benzene with acetyl chloride ( CH _3 COCl ) corresponds to Friedel-Crafts acylation. Thus, the reactants involved in Friedel-Crafts alkylation are C _6 H _6 and CH _3 Cl . Answer: C _6 H _6 + CH _3 Cl
