Why is the boiling point of H2Te higher than H2S?
The general increase in boiling point from H2S to H2Te or from HCl to HI is caused by increasing London forces between molecules due to an increasing number of electrons.
Which has highest boiling point H2O H2S H2Se H2Te?
So, in H2O , there is intermolecular hydrogen bonding between the oxygen and hydrogen atoms and we know that it is one of the strongest forces. Therefore, H2O will have the highest boiling point among the given compounds.
Is H2Te more polar than H2S?
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. Smallest H2S = least dispersion forces, largest = H2Po = strongest dispersion forces.
What is the boiling point of H2Te?
Hydrogen telluride/Boiling point
Does H2Te or H2S have a higher boiling point?
H2Te has the highest molecular weight and thus it has the highest boiling point from H2S and H2Se.
Which has higher boiling point H2O or H2S?
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.
Which is stronger H2Se or H2Te?
Among H2S, H2Se, H2Te the strongest acid is H2Te. The reason being that the bond strength in it the weakest so it dissociates easily.
Does H2Te has a high boiling point?
Amongst H2O, H2S, H2Se and H2Te, the one with the highest boiling point is (a) H2O because of hydrogen bonding. C4H10 is a nonpolar hydrocarbon molecule so has the dispersion force (42 electrons) and has a stronger force of attraction than CO2 (bp −0.5°C).
Is H2S or HS a strong acid?
Organic chemists customarily compare the strength of bases using the strengths of their conjugate acids, measured as pKa. HF is a stronger acid than H2S. The stronger the acid, the weaker the conjugate base, and vice versa. Thus, HS ¯ is a stronger base than F ¯.
Which acid is strongest among H2O H2Te H2Se H2S?
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. The order is therefore H2O < H2S < H2Se < H2Te.
