Assertion : Benzoic acid is stronger acid than acetic acid.
Reason : `K_(a)` for benzoic acid is `6.5xx10^(-5)` and for acetic acid is `1.74xx10^(-5)`.

Explanation

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.
