Which has the highest boiling point H2S or H2Te?
H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. What is the boiling point of h2s?
Why does water have a higher boiling point than hydrogen sulfide?
Thus, even though a water molecule has less mass than a hydrogen sulfide molecule, water has a higher boiling point due to the intermolecular hydrogen bonding forces that exist in water.
Why does H2S have more H bondings than H2O?
In H2O and H2S , Oxygen and Sulphur are the central atoms respectively.Among Oxygen and Sulphur , Oxygen is more electronegative(tendency to gain electrons) and hence it can form more number of intermolecular H bonding with other water molecules than Sulphur in H2S. More the number of H bondings ,...
Why is H20 a liquid and H2S a gas?
H2O is liquid because of its ability to form hydrogen bonds which is possible only in case of F , O and N because of their high electronegativity. While in case of H2S there is no hydrogen bond formation . Hence H20 is liquid while H2S is gas .
Why is h20 boiling point higher than H2S?
Between water and hydrogen sulfide, both are polar, and have dipole-dipole forces, so they have higher boiling points than methane or silane. But water has hydrogen bonds, which are extra-strong dipole-dipole forces. Water boils much hotter than hydrogen sulfide.
Which is H2O and H2S has higher boiling point?
H2O has higher boiling point than H2S because.
Why is the boiling point of H2S lower than H2O?
H2S molecules are involved in weaker hydrogen bonding than H2O molecules. This is because of the lower electronegativity of sulphur than oxygen. So, less energy is required to break the hydrogen bonds in H2S. Thus, the boiling point of H2S is lower than that of H2O.
Why H2O has higher boiling point?
Water molecule through its extensive hydrogen bonding forms a bulky molecule and it is very difficult to break its bonds. A large amount of energy is required to break all its bonds. Thus H2O has a higher boiling point than HF.
Which has a higher surface tension H2O or H2S?
d) Water has a higher surface tension compared to H2S. e) Water has a higher viscosity compared to H2S. 15. Ethyl ether molecules experience only London dispersion forces whereas hydrogen sulfide (H2S) molecules experience dipole forces.
Why H2S has a lower boiling point than H2O and H2Se?
Why does H2S has lower boiling point than H2S? Sulfur is not nearly as electronegative as oxygen so that hydrogen sulfide is not nearly as polar as water. Because of this, comparatively weak intermolecular forces exist for H2S and the melting and boiling points are much lower than they are in water.
Which has stronger intermolecular forces H2S or H2O?
H2O has hydrogen bonding, so it is stronger than H2S. These compounds are all the same shape, and are all non-polar. Therefore, the difference in London dispersion forces are more important for these compounds.
Which has a higher boiling point H2S or H2Se?
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.
