Acidic character$\propto$stability of conjugate base (anion)

Stability of anion$\propto –\text{I}$

Hence greater the$–\mathrm{I}$effect greater will be the acidity

Order of$-\mathrm{I}$effect$-{\mathrm{NO}}_2>\mathrm{CN}>-\mathrm{F}>-\mathrm{Cl}$Hence, the order of acidity$\left({\mathrm{k}}_{\mathrm{a}}\right)$will be

${\text{O}}_2{\text{NCH}}_2\text{COOH}>{\text{NCCH}}_2\text{COOH}>{\text{FCH}}_2\text{COOH}>{\text{Cl CH}}_2\text{COOH}$
