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? H2S molecules are involved in weaker hydrogen bonding than H2O molecules. In H2O and H2S , Oxygen and Sulphur are the central atoms respectively.Among Oxygen and Sulphur , Oxygen is more electronegative (tendency to gain electrons) and hence it can form more number of intermolecular H bonding with other water molecules than Sulphur in H2S.

When compared to H2S H2O has a higher boiling point because H2O contains stronger? vaporized on boiling consisting on average of several water And hence, greater will be the boiling point of that liquid. Only emails and answers are saved in our archive. Hydrogen sulfide is a gas at standard conditions. What bank can you exchange foreign money? Top Steph Du 1H Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water. 15. This is because of the lower electronegativity of sulphur than oxygen. And we all know that the boiling point of water is 100C. [8][12], Despite being highly toxic, no human fatalities have yet been reported. JavaScript is disabled. 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.

When I was much younger, I worked in an inorganic lab whose specialty was inorganic sulfides and selenides. molecular weight than hydrogen selenide, the unit that must be Does H2O or H2Se have a higher boiling point? Therefore, despite the fact that HCl molecules can form stronger hydrogen bonds between themselves, the intermolecular attractions between H2S molecules still prevail as they are twice as numerous. In the final review session, Lyndon said that H2Se has a greater boiling point (and therefore stronger bonds) because it has greater London dispersion forces than H2S does. 9 Which is the correct order for boiling point? H2S is more polar than H2Se because H2S has greater dipole-dipole forces than H2Se since the H-S bond is more polar than the H-Se bond.

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. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. Boiling points of the lower hydrides follow the order we would expect for dispersion forces. H2Se has the higher boiling point because it has a larger mass and more electrons. The. The increase in boiling point happens because the molecules are getting larger with more electrons, and so van der Waals dispersion forces become greater.
