The correct sequence of acidic strength of the following aliphatic acids in their decreasing order is:
 \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}, \mathrm{CH}_{3} \mathrm{COOH},\)
 \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH}, \mathrm{HCOOH}\)
(Jee Main 2024)
  1. \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH}\) >\(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}\)> \(\mathrm{CH}_{3} \mathrm{COOH}\) > \(\mathrm{HCOOH}\)
  2. \(\mathrm{CH}_{3} \mathrm{COOH}\)>\(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}\)> \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH}\) > \(\mathrm{HCOOH}\)
  3. \(\mathrm{HCOOH}\) > \(\mathrm{CH}_{3} \mathrm{COOH}\) > \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}\)
     > \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH}\)
  4. \(\mathrm{HCOOH}\) > \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{COOH}\) > \(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COOH}\) > \(\mathrm{CH}_{3} \mathrm{COOH}\)

Answer

(C) HCOOH > CH _ 3 COOH > CH _ 3 CH _ 2 COOH > CH _ 3 CH _ 2 CH _ 2 COOH
