As per your syllabus, Friedel-Crafts ACYLATION of benzene uses an acyl halide + AlCl₃ to generate which electrophile?
ACarbanion R⁻ alone
BCarbene R₂C: alone
CAcylium (RC⁺=O ion)
DFree-radical R• alone
Answer & Solution
Correct answer: C. Acylium (RC⁺=O ion)
Your syllabus: RCOCl + AlCl₃
→ RC⁺=O + AlCl₄⁻ (acylium ion attacks benzene to give acyl benzene).
