Answer 25

alkanes get less acidic with increasing number of carbons. think of inductive effect. destabilization of conjugate.
Also, the more s character the more acidic the molecule is due to stabilization of the negative charge. s orbitals are held closer to the nucleus than p orbitals. When there is more s character, the negative charge is closer to the nucleus, which is positively charged, and thus is stabilized more. Therefore Alkynes are more acidic than alkenes or alkanes.
