Answer:
Conjugate base of chloroacetic acid will be weakest.
Explanation:
of an acid is a parameter to predict it's acidic strength.
Higher the
, higher will be acid dissociation . Hence acidity will be higher.
We know that the stronger an acid, the weaker it's conjugate base. So higher the
value of an acid, weaker will be it's conjugate base.
The order of
value: 
So, conjugate base of chloroacetic acid will be weakest.
