which is more acidic among alkanes,alkenes and alkynes?does it depend on the number of free h ions?justify

Alkanes get less acidic with more carbons, because of +I [INDUCTIVE EFFECT] effect of long carbon group, which destabilize its conjugate base and thus corresponding conjugate acid is weak, and hence ACIDITY OF ALKANES DECREASES WITH INCREASE IN CARBON CHAIN.
