**Aryl halides are prepared** by direct halogenation of arenes with which catalyst?

  1. Pd/C
  2. Na metal
  3. Anhydrous Lewis acid (e.g. FeCl₃, AlCl₃, FeBr₃)
  4. Concentrated H₂SO₄
Show answer and solution

Correct answer: C. Anhydrous Lewis acid (e.g. FeCl₃, AlCl₃, FeBr₃)

**Electrophilic aromatic substitution:** Lewis acid (FeX₃, AlCl₃) activates X₂ by polarising it. Generates electrophile X⁺ that attacks the aromatic ring. Direct halogenation with Cl₂/Br₂ works F₂ is too reactive, I₂ needs oxidant to drive the equilibrium.
