C20H40 contains a much longer hydrocarbon chain. Because of this there is more energy from van der Waals interactions between neighboring hydrogen atoms. C4H8 has fewer of these interactions and is easier to boil because less energy is required to overcome the effect of these van der Waals interactions.
