Why are alkynes more acidic in nature?
Terminal alkynes are acidic with respect to water. If the alkyne is not terminal it can’t have easily available free oxygen to loose, so it can’t act as Arrhenius acid.
Further the acidity increase in presence of electron withdrawing or aromatic group or any group facilitating release of terminal H from alkyne group.

Only terminal alkynes (eg. Ethyne) are acidic. It is because the terminal C-atom in terminal akynes is bonded with H-atom. This C-atom is sp hybridised and electronegativity is proportional to the %s character because these orbitals are closer to the nucleus. Hence, H^+ can be donated easily.
