Question

Q. Among the following the strongest acid is
(A) $\mathrm{CH}_{3} \mathrm{COOH}$
в $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH}$
c $m-\mathrm{CH}_{3} \mathrm{OC}_{6} \mathrm{H}_{4} \mathrm{COOH}$
D $p-\mathrm{CH}_{3} \mathrm{OC}_{6} \mathrm{H}_{4} \mathrm{COOH}$

Answer 1

Solution:
$\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH}$ is the strongest acid. In $m-\mathrm{CH}_{3} \mathrm{OC}_{6} \mathrm{H}_{4} \mathrm{COOH}$ and $p-\mathrm{CH}_{3} \mathrm{OC}_{6} \mathrm{H}_{4} \mathrm{COOH}$, the $-\mathrm{OCH}_{3}$ group' being electron donating makes benzoic acid weaker.
