Question

The weaker acid among the following is:
  1. CH3COOH
  2. Cl3CCOOH
  3. ClCH2COOH
  4. (CH3)2CHCOOH

A
ClCH2COOH
B
CH3COOH
C
(CH3)2CHCOOH
D
Cl3CCOOH
Solution
Verified by Toppr


Due to +R effect of 2 methyl groups the stability of the anion formed after release of H+ is very less.

Hence option D is weak acid.

Option D is correct.
