For the following carboxylic acids, (i) F ₃ CCOOH (ii) CH ₃ COOH (iii) C ₆ H ₅ COOH (iv) CH ₃ CH ₂ COOH The correct order of p K_a values is

Options

  1. Ai > iii > ii > iv
  2. Biv > ii > iii > i
  3. Civ > iii > ii > i
  4. Di > ii > iv > iii

Correct answer

B. iv > ii > iii > i

Step-by-step solution

The order of acidity is : So, the order of p K_a values is (iv) > (ii) > (iii) > (i)
