Chemical, physical and thermal properties of hydrogen sulfide:Values are given for gas phase at 25oC /77oF / 298 K and 1 bara, if not other phase, temperature or pressure given. 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. Why does H2Se have a higher boiling point than H2S? 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. This problem has been solved! If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords. What I dont understant is that H2S has the strongest dipole dipole interaction and since dipole-dipole interaction is stronger than dispersion force, H2S really should have higher boiling point than H2Se but why is it the opposite? It is the most toxic selenium compound with an exposure limit of 0.05 ppm over an 8-hour period. Study with Quizlet and memorize flashcards containing terms like Arrange these compounds in order of increasing boiling point H2S, H2Se, H2O (a) H2O < H2Se < H2S (b) H2Se < H2S < H2O (c) H2Se < H2O < H2S (d) H2S < H2Se < H2O (e) H2O < H2S < H2Se, Which of the following would be expected to form a homogenous solution?

Does having more london dispersion forces make a molecule stronger, or more likely to ionize? 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 .
