Ethyne

Vedclass · Answer

(A) The acidic nature of hydrogen in hydrocarbons depends on the hybridization of the carbon atom to which it is attached.In $CH \equiv CH$ (Ethyne),the carbon is $sp$ hybridized,which has $50\%$ $s$-character,making it more electronegative and thus the $C-H$ bond is polar,allowing the hydrogen to be acidic.Reaction with sodium metal confirms this: $2CH \equiv CH + 2Na 	o 2CH \equiv C^{-}Na^{+} + H_2 \uparrow$.Therefore,ethyne has acidic hydrogen.
