Why is London Disperse Force in every bond? 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.

This essentially means H2Se is a bigger molecule than H2S meaning the Van Der Waal forces (London forces) on H2Se is stronger than on H2S which means it takes more energy to break the intermolecular forces for H2Se than H2S- this leads to H2S having the lower boiling point. This in turn will increase the energy needed to pull the molecules apart, thus an increase in the boiling point . Copyright 2023 Quick-Advices | All rights reserved. Which is stronger H2Se or H2S? However, I feel like I'm missing something. In this case, look at the molecular weight. Water has a higher boiling point than hydrogen sulphide. This is because of the lower electronegativity of sulphur than oxygen. [4][5] Even at extremely low concentrations, this compound has a very irritating smell resembling that of decayed horseradish or 'leaking gas', but smells of rotten eggs at higher concentrations.

Sonoda, N.; Kondo K.; Nagano, K.; Kambe, N.; Morimoto, F. Angewandte Chemie International Edition English 1980, vol. Hydrogen selenide/Boiling point. [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. 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.

Hydrogen sulfide/Boiling point. Analytical cookies are used to understand how visitors interact with the website. These cookies will be stored in your browser only with your consent. Similarly, it is asked, which has the highest boiling point h2o h2s or H2Se? SOAS Paul Robeson House - what's it like? The gas can be detected at a level of 2 parts per billion. So, in $ {H_2}O $ , there is intermolecular hydrogen bonding between the oxygen and hydrogen atoms and we know that it is one of the strongest forces. According to the Sonoda method, H2Se is generated from the reaction of H2O and CO on Se in the presence of Et3N. However, it is observed that the boiling point of H2O is highest among these hydrides.
