Although very pungent at first, it quickly deadens the sense of smell. 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. 1 Why boiling point of H2O is higher than H2S and H2Se? Why is London Disperse Force in every bond? Bond angle of H2O is larger because oxygen is more electronegative than sulphur therefore bond pair electron of OH bond will be closer to oxygen and there will be more bond-pair bond-pair repulsion between bond pairs of two OH bonds. In the laboratory, H2Se is usually prepared by the action of water on Al2Se3, concomitant with formation of hydrated alumina. High boiling point and low melting point.

Hydrogen sulfide, H2S, is ahighly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. At the critical point there is no change of state when pressure is increased or if heat is added. What is the boiling point of H2Se? For a better experience, please enable JavaScript in your browser before proceeding. 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. It does not store any personal data. 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. A teacher walks into the Classroom and says If only Yesterday was Tomorrow Today would have been a Saturday Which Day did the Teacher make this Statement? Hydrogen sulfide occurs naturally in crude petroleum, natural gas, volcanic gases, and hot springs. 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.

History Hydrogen sulfide has been known since early times. of H 2O is much higher than that of H 2S. For a given pressure, different liquids will boil at different temperatures. Answer (1 of 14): Summary; Oxygen is more electronegative than sulphur Thus, the dipoles (which have a lot to do with bonding) are more strongly charged in H2O Thus the intermolecular bonds formed in H2O are stronger Thus it takes more energy to break those bonds in H2O Thus, to break those . Some of our calculators and applications let you save application data to your local computer. -76F (-60C) 6 Which water has the highest boiling point?

The effect of hydrogen bonding is significantly less for the other elements of the chalcogenide group. So, less energy is required to break the hydrogen bonds in H2S. As a result, both melting and boiling point of water are higher than those of hydrogen sulphide. 212F (100C) Among H2S, H2Se, H2Te the strongest acid is H2Te. Boiling point of H2S is about -76 deg. Why boiling point of H2O is higher than H2S and H2Se? This is because of the lower electronegativity of sulphur than oxygen.
