The correct increasing order of acidities is: Cl _ 3 CCOOH, Cl _ 2...

The correct increasing order of acidities is:
Cl3CCOOH,Cl2CHCOOH,ClCH2COOH{Cl}_{3}CCOOH, {Cl}_{2}CHCOOH, {ClCH}_{2}COOH

Options

  1. A1<2<31 < 2 < 3
  2. B2<1<32 < 1 < 3
  3. C3<2<13 < 2 < 1
  4. DIt cannot be determined.

Correct answer

A. 1<2<31 < 2 < 3

Step-by-step solution

Greater the number of electron-withdrawing substituents for a conjugate base, more is the stability of conjugate base. More the stability of conjugate base, more is the acidity. Here, chlorine is an electron-withdrawing group. Thus, the order of acidity is,
1<2<31 < 2 < 3
