The correct answer is:
2 , 2-dichloroacetic acid $>2$-chloropropanoic acid $>3$-chloropropanoic acid $>$ propanoic acid
Acidic strength $\propto k_{a}$ values
Due to - I-effect of electron withdrawing - Cl group, chloropropanoic acid is stronger acid than propanoic acid. Further, greater the number of electron withdrawing substitutents, greater would be the acidic strength.
Inductive effect decreases rapidly with distance and so, is the acidic strength. Hence, the correct order of acidic strength (or $k_{a}$ values) will be
