The correct increasing order of acidities is: Cl 3 CCOOH ,   Cl 2 CHCOOH ,   ClCH 2 COOH
Options
- A1 < 2 < 3
- B2 < 1 < 3
- C3 < 2 < 1
- DIt cannot be determined.
Correct answer
A. 1 < 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 < 3
