Ethyne

Vedclass · Answer

(A) The terminal alkyne,ethyne $(CH \equiv CH)$,contains acidic hydrogen because the $sp$-hybridized carbon atom is more electronegative,pulling the electron density of the $C-H$ bond towards itself. This allows the hydrogen to be removed by strong bases or reactive metals like sodium: $2CH \equiv CH + 2Na \rightarrow 2CH \equiv C^{-}Na^{+} + H_2$ Thus,ethyne shows acidic character.
