Per NCERT §9.5.5(iv), Friedel-Crafts ALKYLATION of benzene uses which reagent system?
AR-Cl with anhydrous AlCl₃
BR-Cl with Na in dry ether
CROH with conc. H₂SO₄
DR-COOH with NaOH/CaO
Answer & Solution
Correct answer: A. R-Cl with anhydrous AlCl₃
NCERT §9.5.5(iv): alkyl halide + anhydrous AlCl₃ generates R⁺, which attacks benzene to form alkylbenzene.
