A

1.B < C < D < A

B

2.C < B < A < D

C

3.NOT IN OPTION

D

4.B < C < A < D

Text Solution

Verified by Experts

The correct Answer is:
D
More the acidic strength, lesser will be the value of `pK_(a)`
is most acidic as it’s conjugate base is resonance stabilized by `NO_(2)` group
Overall order of acidic strength

Order of `pK_(a)` : `B lt C lt A lt D` Conjugate base is destabilized by +M of –OMe, hence least acidic
