As the s character increases, the electronegativity of the carbon atom also increases. As a result, there is a development of partial charges in the C-H bond.
increasing order of s character-

sp^3<sp^2<sp

More is the s character, more is the acidic nature of the compound.
So, the decreasing order of acidic behaviour is-
ethyne(50% s) >benzene(33% s) > hexane(25% s)
