What does it mean that the Bible was divinely inspired? 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. For full table with Imperial Units - rotate the screen! However, in the chemistry textbook version 6 p.484, H2Se is expected to be a stronger acid than H2S because H2Se has weaker bonds. On the other hand, H2Se and H2Te contain hydrogens that are not attached to electronegative elements, so they cannot undergo hydrogen bonding, and they possess boiling points that are significantly lower than water. .

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. And we all know that the boiling point of water is 100C. Water molecules experience hydrogen bonds whereas hydrogen sulfide (H2S) molecules experience dipole forces. H2Se has the higher boiling point because it has a larger mass and more electrons. Please read Google Privacy & Terms for more information about how you can control adserving and the information collected.

What is the melting point of H2S?-85.5 C Hydrogen sulfide/Melting point. h2s vs h2se boiling point H2O, 100oC; H2S, -60oC; H2Se, -41oC; H2Te, -2oC (2 marks) Generally, the boiling points in a series increases with the molecular mass and this would put the boiling point of water below -60o C. The boiling point of water is high because of the extensive H-bond between the water molecules. 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 .
