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. When looking at what has a higher boiling point, we look at what has the strongest intermolecular forces. 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. 1 Why boiling point of H2O is higher than H2S and H2Se? In the 19th . 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. Bigger london dispersion forces do lead to higher boiling points when a molecule exhibits no hydrogen bonds, is not polar or when the polarity is almost the same between two molecules. Why is H2Se stronger than H2S? Thus, the boiling point of H2S is lower than that of H2O. Liquids are not easily compressed. Liquids have much higher densities in comparison to gases. 3 Why does H2S have a lower boiling point than H2O? The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. Can someone explain to me why H2Se would have the higher boiling point? Since electrons are constantly moving, at any given time, one atom will be more electronegative than the other atom. Is H2Te stronger than H2Se? Therefore, 1-chloropentane has the highest boiling point. [10] H2Se can be purchased in cylinders. Which is the most effective way to prevent viral foodborne illnesses? Amongst H2O, H2S, H2Se and H2Te, the one with the highest boiling point is (a) H2O because of hydrogen bonding. This is a result of the significant hydrogen bonding present in the water molecule. The Student Room and The Uni Guide are both part of The Student Room Group.

Boiling point of H2S is about -76 deg. H2S < H2Se < H2Te < H2O This is the correct boiling point order. Which has a higher boiling point H2O or H2S? [7], Industrially, it is produced by treating elemental selenium at T>300C with hydrogen gas. And hence, greater will be the boiling point of that liquid. 1 Why is H2Se have a higher boiling point than H2S? Molecules with hydrogen bonds will always have higher boiling points than similarly sized molecules which dont have an an -O-H or an -N-H group. 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. This is because of the lower electronegativity of sulphur than oxygen. 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.
