Chemistry - Nomenclature Question with Solution | TestHub

The acid strength of conjugate acid is
$\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_3<\mathrm{H}\mathrm{C}\equiv \mathrm{C}\mathrm{H}<\mathrm{C}{\mathrm{H}}_3\mathrm{C}{\mathrm{H}}_2\mathrm{O}\mathrm{H}$
Hence, the order of basic strength is
${\text{CH}}_{\text{3}}{\text{CH}}_{\text{3}}{\text{O}}^{-}\text{<}\text{HC}\equiv {\text{C}}^{-}\text{<}{\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}^{-}$
