Maximum decarboxylation occurs in

Options

  1. ACH ₃ COOH
  2. BC ₆ H ₅ COOH
  3. CC ₆ H ₅ CH ₂ COOH
  4. DCH ₃ COCH ₂ COOH

Correct answer

D. CH ₃ COCH ₂ COOH

Step-by-step solution

CH ₃ COCH ₂ COOH is a -keto acid. Thus decarboxylation is maximum in a carboxylic acid containing an electron withdrawing group such as > CO or - COOH at the -carbon atom with respect to the - COOH group.
