Why is the boiling point of h2s lower than h2o? Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.
Why H2S has a lower boiling point than h20? H2S molecules are involved in weaker hydrogen bonding than H2O molecules. This is because of the lower electronegativity of sulphur than oxygen. So, less energy is required to break the hydrogen bonds in H2S. Thus, the boiling point of H2S is lower than that of H2O.
Why h20 has higher boiling point than H2S? Water has a higher boiling point than hydrogen sulphide. The intermolecular attractions between water molecules are stronger than H2S molecules due to hydrogen bonding in H2O due to high electronegativity and small size of oxygen atom.
Why does H2S have a lower boiling point than h20 and H2Se? By comparing H2O with H2S, H2Se and H2Te, we can see that the boiling points will increase from H2S to H2Te because of the increasing molecular weights. That means H2O is supposed to have a lower boiling point then H2S, but the opposite can be observed and thus be explained by the formation of strong hydrogen bonds.
Why is the boiling point of h2s lower than h2o? – Related Questions
Why does water have higher boiling point than ethanol?
Hydrogen bonding is stronger in water than in ethanol. Positive H complements the negative electron pairs in O and, thus, forming a stronger intermolecular force. Water needs higher energy to break those bonds. Hence, water has higher boiling point at same atmospheric pressure than ethanol.

What is the difference in raw and boiled linseed oil?
The difference between Raw and the Boiled Linseed Oils is that Raw Linseed Oil has a longer drying time, where as Boiled Linseed Oil has been treated by blowing hot air through the liquid – this shortens its drying time considerably.
