The increasing order of the acidity of the

Question:

The increasing order of the acidity of the $\alpha$-hydrogen of the following compounds is :

  1. $(\mathrm{D})<(\mathrm{C})<(\mathrm{A})<(\mathrm{B})$

  2. $(B)<(C)<(A)<(D)$

  3. $(\mathrm{A})<(\mathrm{C})<(\mathrm{D})<(\mathrm{B})$

  4. $(C)<(A)<(B)<(D)$


Correct Option: 1

Solution:

(a) Acidity $\propto$ stability of conjugate base

Thus increasing order of acidity is $\mathrm{D}<\mathrm{C}<\mathrm{A}<\mathrm{B}$.
