Which of the following reaction is feasible?

Options

  1. AH ₃ CCH = CHCH ₂ OH PCC H ₃ CCH = CHCHO
  2. BCH ₃ CH ₂ CH ₂ OH KMnO ₄ H ⁺ H ₃ CCH ₂ CHO

Correct answer

B. CH ₃ CH ₂ CH ₂ OH KMnO ₄ H ⁺ H ₃ CCH ₂ CHO

Step-by-step solution

Reaction in (a) is not feasible because replacement of - OH by - Cl is not possible for phenol due to partial C = O bond and resonance stabilization. Reaction is (c) is not feasible because KMnO ₄ is a strong oxidizing agent and converts - C - OH to - COOH . Reaction in (d) is not feasible because 20 % PO ₄ is not a strong enough dehydrating agent and therefore 85 % ~h ₃ PO ₄ is used.
