Solution

The correct option is A

IV < I < III < II


Here the substituents are present in m - position, so they will not show any mesomeric effect; only inductive effect operates, NO2 group has + cahrge on N, so it has more a electron - withdrawing inductive effect than Cl; m - nitrophenol will be more acidic than m - chlorophenol. Methyl group is acid weakening group. Hence the relative acidic strength is
m - cresol < phenol < m - chlorophenol < m - nitrophenol
IV I III II
