Among H2S, H2Se, H2Te the strongest acid is H2Te. 212F (100C) 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. vaporized on boiling consisting on average of several water Why does H2S have a lower boiling point than H2O and H2Se? F. The (unusually) high boiling point of H2O is explained by extensive hydrogen bonding in water. Sulfur is not from these elements, therefore the dipole-dipole force between 2H2S is not a hydrogen bond. Which of the following has highest boiling point? The bigger the atom, the greater the shift in electrons to create a temporary dipole and makes H2Se a stronger acid. 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. Similarly, it is asked, which has the highest boiling point h2o h2s or H2Se? 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? How do I choose between my boyfriend and my best friend? 4 Which of the following has highest boiling point H2O H2S?
