Question
Why is benzoic acid a stronger acid than acetic acid?
✓
Answer
The $K _a$ value of benzoic acid $\left(6.3 \times 10^{-5}\right)$ is more than that of acetic acid $\left(1.75 \times 10^{-5}\right)$. Actually, $C _6 H _5$ group with -I effect it facilitates the release of $H ^5$ from benzoic acid while $CH _3$ group with + I effect tends to retard it.
