Consistent with this structure, three IR-active vibrational bands are observed: 2358, 2345, and 1034cm1. This is because of the lower electronegativity of sulphur than oxygen. Boiling point of H2S is about -76 deg. 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? 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?

This cookie is set by GDPR Cookie Consent plugin. When looking at what has a higher boiling point, we look at what has the strongest intermolecular forces. H2Se is a colorless, flammable gas under standard conditions. On the other hand, H2Se and H2Te contain hydrogens that are not attached to electronegative elements, so they cannot undergo hydrogen bonding, and they possess boiling points that are significantly lower than water. Thus, the boiling point of H2S is lower than that of H2O. This is because of the lower electronegativity of sulphur than oxygen. This is due to the hydrogen bonding exhibited by the molecules of water. These cookies will be stored in your browser only with your consent. 5 Why does H2Se have a higher boiling point than H2S? Since S, Se, Te are in the same group of the periodic table - so they have the same type of forces/bonding.

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 H2O and H2Se? This website uses cookies to improve your experience while you navigate through the website. Its decomposition is used to prepare the highly pure element. We also use third-party cookies that help us analyze and understand how you use this website. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water. . Note: We should remember that volatility is inversely proportional to the boiling point of the liquid. . Hydrogen sulfide/Boiling point. Among H2O, H2, H2Se and H2 Te, the one with highest boiling point is a)H2O because of hydrogen bond. This leads to water having a higher boiling point than if there were only weaker dipole-dipole forces. 19, page 308, National Institute for Occupational Safety and Health, http://www.epa.gov/ttnatw01/hlthef/selenium.html, "CDC - Immediately Dangerous to Life or Health Concentrations (IDLH): Hydrogen selenide (as Se) - NIOSH Publications and Products", https://www.cdc.gov/niosh/docs/81-123/pdfs/0336.pdf, https://www.osha.gov/dts/chemicalsampling/data/CH_246700.html, WebElements page on compound's properties, CDC - NIOSH Pocket Guide to Chemical Hazards, https://en.wikipedia.org/w/index.php?title=Hydrogen_selenide&oldid=1133328984, This page was last edited on 13 January 2023, at 07:04. e) Water has a higher viscosity compared to H2S. Which has a higher boiling point H2O or H2S? vaporized on boiling consisting on average of several water [6], The properties of H2S and H2Se are similar, although the selenide is more acidic with pKa = 3.89 and the second pKa = 11,[6] or 15.05 0.02 at 25C. This cookie is set by GDPR Cookie Consent plugin. H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. It is heavier than air and tends to accumulate at the bottom of poorly ventilated spaces. Bernd E.
