Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A : Order of acidic nature of the following compounds is  A > B > C.

Reason R: Fluoro is a stronger electron withdrawing group than Chloro group.

In the light of the above statements, choose the correct answer from the options given below :

 

Options:

Answer:
D
Solution:

The electron withdrawing groups decreases the acidic nature and The electron releasing groups increases the acidic nature.

The F & Cl are electron withdrawing while CH3 is electron loosing hence acidic strength will be

On further differentiation the– I effect depends on most importantly over distance hence.

The F has higher –I effect as compared to Cl hence reason is correct statement but the –I effect depends more on distance as compared to power hence  is stronger acid than
