Chemistry - Ionic Equilibrium Question with Solution | TestHub

According to Bronsted Lowry concept.
strength of conjugate base$\propto \frac{1}{\mathrm{s}\mathrm{t}\mathrm{r}\mathrm{e}\mathrm{n}\mathrm{g}\mathrm{t}\mathrm{h} \mathrm{o}\mathrm{f} \mathrm{a}\mathrm{c}\mathrm{i}\mathrm{d}}$
Strength of acid is as follows
$\mathrm{H}\mathrm{C}\mathrm{l}>\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{O}\mathrm{H}>{\mathrm{H}}_2\mathrm{O}$
So the correct order of strength of bases follows the order
$\mathrm{O}{\mathrm{H}}^{-}>\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}{\mathrm{O}}^{-}>\mathrm{C}{\mathrm{l}}^{-}$
