Hydrogen atoms in ethyne (HC ≡ CH) are attached to the sp hybridised carbon atoms which is more electronegative. Thus, hydrogen atom can be liberated as proton more easily and ethyne behaves as an acid.

Hydrogen atoms in ethyne $(H C \equiv C H)$ are attached to the $s p$ hybridised carbon atoms which is more electronegative. Thus, hydrogen atom can be liberated as proton more easily and ethyne behaves as an acid.
