Water has a higher boiling point than hydrogen sulphide. The intermolecular attractions between water molecules are stronger than H2S molecules due to hydrogen bonding in H2O due to high electronegativity and small size of oxygen atom.
Why the boiling point of H2S is less 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.
Which has higher boiling point H2O H2S?
Among H2O,H2S,H2Se and H2Te, the one with the highest boiling point is H2O because of intermolecular hydrogen bonding which leads to molecular association and leads to higher energy for boiling.
Why does H2O have a higher boiling point than N2?
it is because h2o can form hydrogen bonds. while N2 cannot. Thus H2O has a stronger intermolecular force than N2. that’s why H2O has a higher boiling point.
Why does H2S have a lower boiling point than 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.
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 one has the highest and lowest boiling point respectively H2O H2S?
H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se. H2O ought to have the lowest boiling point but it doesn’t because of hydrogen bonding. Hydrogen Sulfide is -76*c. and is the minimum.
Which one has the lowest boiling point respectively H2O H2S?
Explanation. H2O > H2Te > H2Se > H2S. Hence H2S has the lowest boiling point.
Which of the following has highest boiling point?
Xe has the highest atomic size and molecular weight. Hence, it has strong van der waal’s forces of attraction. Hence, it has the highest boiling point.
Which has a higher boiling point H2O or ch4?
Water has a higher boiling point because the hydrogen bonds that form among water molecules are stronger than the Van der Waals interactions among methane molecules, thus more energy must be provided in order to break the hydrogen bonds and allow the water molecules to escape the liquid state.
Which has higher boiling point no or N2?
This means that partial, temporary charge created in O2 is of greater magnitude than that of N2. NO is a polar molecule. Polar molecules have dipole-dipole forces. Dipole-dipole forces are stronger than London Dispersion forces, so NO has the highest boiling point.
Why is boiling point of H2O higher than ch4?
Because oxygen is more electronegative than carbon, an O-H bond has a larger bond dipole than a C-H bond. Hence the force of attraction between two water molecules is greater than it is between two methane molecules. Water has the higher boiling point. Now let’s compare methane and dihydrogen.
Which is stronger H2S or H2Se?
In binary acids such as H2S and H2Se, the H–Se bonds is longer than the H–S bonds as Se is larger than S. The H–Se bond is therefore weaker than the H–S bond and H2Se is thus a stronger acid than H2S.
Why H2Se has higher melting point than H2S?
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.
Which of the following has lowest boiling point among H2O H2S H2Se and H2Te?
H2S
