    Boiling point comparison between of H2S, H2Se, H2Te

    So the actual trend here is H2S<H2Se<H2Te. What I dont understant is that H2S has the strongest dipole dipole interaction and since dipole-dipole interaction is stronger than dispersion force, H2S really should have higher boiling point than H2Se but why is it the opposite?
