Sulfur is not from these elements, therefore the dipole-dipole force between 2H2S is not a hydrogen bond. So, less energy is required to break the hydrogen bonds in H2S. It does not store any personal data. H 2Se because of lower molecular weight Medium Solution Verified by Toppr Correct option is A) Among H 2O,H 2S,H 2Se and H 2Te, the one with the highest boiling point is H 2O because of intermolecular hydrogen bonding which leads to molecular association and leads to higher energy for boiling. Increasing order of acidity is : H 2O<H 2S<H 2Se<H 2Te Solve any question of Chemical Bonding and Molecular Structure with:- Patterns of problems > H2O molecules can pack together more closely. So, less energy is required to break the hydrogen bonds in H2S. 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. High boiling point and low melting point. 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.
