(1) The hydrogen bonding ability of H 2 O which increases the boiling point.The partial charges, induced by the higher electronegativity of oxygen, mean that the hydrogens and oxygens will be attracted to one another by coloumbic forces. So I initially thought, since S has a higher electronegativity than Se, H2S would have the higher boiling point. Why does sulfur have a higher boiling point than water? 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.

Hydrogen sulfide, H2S, is a highly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. Which of the following has highest boiling point H2O H2S? [4], Except where otherwise noted, data are given for materials in their. This is because of the lower electronegativity of sulphur than oxygen. It adds across alkenes. If true enter 1 else 0. Why does water have a higher boiling point than hydrogen selenide? The. H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. This is due to the hydrogen bonding exhibited by the molecules of water. This cookie is set by GDPR Cookie Consent plugin. However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. Amongst `H_2 O, H_2 S, H_2 Se` and `H_2 Te`, the one with the highest boiling point is: `H_2 O` because of hydrogen bonding, `H_2 Te` because of higher molecular weight, `H_2 S` because of hydrogen bonding, `H_2 Se` because of lower molecular weight.

At the critical point there is no change of state when pressure is increased or if heat is added. So, less energy is required to break the hydrogen bonds in H2S. Copyright The Student Room 2023 all rights reserved. Hydrogen selenide/Boiling point. Thus, there will always be some degree of induced dipole-induced dipole (also known as LDF). It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. In binary acids such as H2S and H2Se, the H-Se bonds is longer than the H-S bonds as Se is larger than S. The H-Se bond is therefore weaker than the H-S bond and H2Se is thus a stronger acid than H2S.
