Why is benzoic acid a stronger acid than acetic acid ?

Text Solution

Verified by Experts

The `K_(a)` value of benzoic acid `(6.3xx10^(-5))` is more than that of acetic acid `(1.75xx10^(-5))`. Actually, `C_(6)H_(5)` group with -I effect facilitates the release of `H^(+)` from benzoic acid while `CH_(3)` group with +I effect tends to retard it. For more details, consult section 16.
