H2O < H2S < H2Se < H2Te Therefore, the boiling point of H2O is expected to be the lowest. It is suspected that this is due to the gas' tendency to oxidise to form red selenium in mucous membranes; elemental selenium is less toxic than selenides are. Amongst H2O, H2S, H2Se and H2Te, the one with the highest boiling point is (a) H2O because of hydrogen bonding. Hydrogen selenide is an inorganic compound with the formula H 2 Se. However, it is observed that the boiling point of H2O is highest among these hydrides. Hydrogen sulfide, H2S, is a highly toxic and flammable, colorless gas with a characteristic odor of rotten eggs. Necessary cookies are absolutely essential for the website to function properly. 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. I'm not sure if the higher electronegativity of S would make the dipole-dipole interaction stronger. Why does H2S have a lower boiling point than H2O?

Knowing that hydrogen bonds are stronger than dipole-dipole forces, this leads to : water has a higher boiling point than hydrogen sulfide because hydrogen bonds are much stronger than dipole-dipole bonds. Explain why H2Se has a higher boiling point than H2S. This is due to the hydrogen bonding exhibited by the molecules of water. Is H2Te stronger than H2Se? 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. Thus, the boiling point of H2S is lower than that of H2O. Liquids have an indefinite shape and assume the shape of their container.

This cookie is set by GDPR Cookie Consent plugin. 11 Which is the correct order for boiling point? 0 votes. Sulfur is not from these elements, therefore the dipole-dipole force between 2H2S is not a hydrogen bond. The chemistry of H2S has been studied since the 1600s. Why does H2S has lower boiling point than H2Se? -86.31F (-65.73C) melting point-85.5 o C: boiling point-60.7 o C: C. History Hydrogen sulfide has been known since early times. 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. The hydrogen sulfide phase diagram shows the phase behavior with changes in temperature and pressure. In binary acids such as H2S and H2Se, the HSe bonds is longer than the HS bonds as Se is larger than S. The HSe bond is therefore weaker than the HS bond and H2Se is thus a stronger acid than H2S. Hydrogen selenide is an inorganic compound with the formula H2Se.
