which one of the following is the correct order of acidic strength? (i) C l 3 C - C O O H (ii) C l 2 C H - C O O H (iii) C l C H 2 - C O O H (iv) C H 3 - C O O H

Options

  1. Aiv >iii > ii >i
  2. Bi > ii >iii >iv
  3. Ci >iii >ii iv
  4. Div >ii > iii >i

Correct answer

B. i > ii >iii >iv

Step-by-step solution

Acidic nature ∝ − I (Electron withdrawing groups) More the − I group at α 'C' of carboxylic acid greater the acidic strength.
