Vedclass · Answer

(C) The acidity of a hydrocarbon depends on the $s$-character of the hybrid orbital of the carbon atom attached to the hydrogen atom.Terminal alkynes,such as $CH_3C \equiv CH$ (propyne),have a hydrogen atom attached to an $sp$-hybridized carbon atom.Due to the high $s$-character $(50\%)$ of the $sp$-hybrid orbital,the electron density is held more tightly by the carbon,making the $C-H$ bond polar and the hydrogen atom acidic.Therefore,$CH_3C \equiv CH$ is an acidic hydrocarbon.
