So I initially thought, since S has a higher electronegativity than Se, H2S would have the higher boiling point. However, I feel like I'm missing something. Can someone explain to me why H2Se would have the higher boiling point? Thanks! Top Steph Du 1H Posts: 106 Joined: Thu Oct 01, …

But there are total 8 valence electrons in H2Se molecule (as calculated in step #1). So the number of electrons left to be kept on the central atom = 8 – 4 = 4. So let’s keep these 4 electrons (i.e 2 electron pairs) on the central atom.
