Vedclass · Answer

(A) The acidity of hydrocarbons depends on the percentage of $s$-character in the hybrid orbitals of the carbon atom attached to the hydrogen.$s$-character $\propto$ Electronegativity of carbon $\propto$ Acidity.For $1$-Alkyne ($sp$ hybridization): $50\% \ s$-character.For Alkene ($sp^2$ hybridization): $33.3\% \ s$-character.For Alkane ($sp^3$ hybridization): $25\% \ s$-character.Therefore,the correct order of acidity is: $1$-Alkyne > Alkene > Alkane.
