Question

What is the correct order of acidity of the protons marked A-D in the given compounds?

• A. $H _{ C }> H _{ D }> H _{ A }> H _{ B }$
• B. $H _{ C }> H _{ D }> H _{ B }> H _{ A }$
• C. $H _{ C }> H _{ A }> H _{ D }> H _{ B }$
• D. $H _{ D }> H _{ C }> H _{ B }> H _{ A }$

Answer 1

Answer: (A)

$H _{ C }> H _{ D }> H _{ A }> H _{ B }$

Answer 2

$\text{acidity of an acid depends upon the stability of its conjugate base.}$

$\text{Hence, the correct option is (A):}$ $H _{ C }> H _{ D }> H _{ A }> H _{ B }$
