Question

The ascending acidity order of the following H atoms is

• A. $C < D < B < A$
• B. $ A < B < C < D $
• C. $ A < B < D < C$
• D. $D < C < B < A$

Answer 1

The Correct Option is A

The given compounds are:

The acidity strength is governed by the stability of the conjugate base. The more stable the conjugate base, the stronger the acid.

Stability of conjugate base α acidic strength

The order of acidity, based on the structure and conjugate base stability, is:

C < D < B < A
Thus, the ascending order of acidity is C < D < B < A.
The Correct Answer is : C < D < B < A
