The hydrocarbon which can react with sodium in liquid ammonia is

Options

  1. ACH ₃ CH ₂ CH ₂ C CCH ₂ CH ₂ CH ₃
  2. BCH ₃ CH ₂ C CH
  3. CCH ₃ CH = CHCH ₃
  4. DCH ₃ CH ₂ C CCH ₂ CH ₃

Correct answer

B. CH ₃ CH ₂ C CH

Step-by-step solution

CH ₃ CH ₂- C CH Na / Liq 9 NH CH ₃ CH ₂ C C Na ^ It is a terminal alkyne, having acidic hydrogen. Note: Solve it as a case of terminal alkynes, otherwise all alkynes react with Na in liq. NH ₃ .
