The correct order of acid character of the following compounds is :

Options

  1. AIV > III > II > I
  2. BII > III > IV > I
  3. CIII > II > I > IV
  4. DI > II > III > IV

Correct answer

B. II > III > IV > I

Step-by-step solution

Presence of electron withdrawing groups such as nitro group enhance the acidic strength of phenol and the presence of electron releasing groups such as alkyl group decreases the acidic strength of phenol. 2 > 3 > 4 > 1
