As the strength of conjugate base α 1/acidic strength
As acidic strength is
$\mathrm{H}\mathrm{O}\mathrm{H}>\mathrm{H}\mathrm{C}\equiv \mathrm{C}\mathrm{H}>\mathrm{N}{\mathrm{H}}_3>\mathrm{C}{\mathrm{H}}_4$
So$\mathrm{C}{{\mathrm{H}}_3}^{-\mathrm{}}>\mathrm{N}{{\mathrm{H}}_2}^{-}>\mathrm{H}–\mathrm{C}\equiv {\mathrm{C}}^{-}>\mathrm{O}{\mathrm{H}}^{-}$
