Which of the following reactions are not feasible? I. CH ₃ CH = CH ₂ HCl ( C ₆ H ₅ CO )₂ O ₂ CH ₃ CH ₂ CH ₂ Cl II. C ₆ H ₆+ CH ₃ CH ₂ CH ₂ Cl AlCl ₃ C ₆ H ₅ CH ( CH ₃ )₂ III. CH ₃ CHClCH ₂ Cl KOH CH ₃ C + CH IV. CH ₃ CH = CHCH ₃ KMnO ₄ / H ⁺ CH ₃ COOH

Options

  1. AI & IV only
  2. BII & III only
  3. CII & IV only
  4. DI & III only

Correct answer

D. I & III only

Step-by-step solution

CH ₃ CH = CH ₂ to CH ₃ CH ₂ CH ₂ Cl in the presence of HCl in a peroxide is not feasible as peroxide/kharash effect is not observed for HCl and HI . feasible as this reaction would give an alkene which when treated with sodamíde gives alkyne. Thus, I and III are not feasible.
