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
- AA is false but R is true
- BBoth A and R are correct and R is the correct explanation of A
- CA is true but R is false
- DBoth A and R are correct but R is NOT the correct explanation of A
Correct answer
D. Both A and R are correct but R is NOT the correct explanation of A
Step-by-step 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 CH 3 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
