Q. Benzene reacts with CH₃Cl in the presence of anhydrous AlCl₃ to form:
A) Chlorobenzene
B) Benzyl chloride
C) Xylene
D) Toluene
Explanation
[Solution from source] This is Friedel–Crafts alkylation: AlCl₃ generates CH₃⁺ which substitutes on the ring, giving C₆H₅CH₃ (toluene). Chlorobenzene would need Cl₂, benzyl chloride needs side-chain chlorination of toluene, and xylene needs a second methylation. Answer (4).
