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.
