Arrange the following in decreasing acidic strength.
Options
- AA > B > C > D
- B  B > A > C > D
- CD > C > A > B
- DD > C > B >   A
Correct answer
A. A > B > C > D
Step-by-step solution
Acidic nature is more, if the stability of the conjugate base is more. Electron withdrawing groups increases the stability. Nitro group at para position shows - M effect and meta position it shows - I effect only. Methoxy group at meta position shows - I effect, but effect is Iess than nitro group. Methoxy group at para position shows + M effect that decreases the acidic nature.
