Q. 55

Why does water show high boiling point as compared to hydrogen sulphide? Give reasons for your answer.

Answer :

This is due to the formation of very stable intermolecular hydrogen bonding(bonding with other molecules of the same or different species) because of the presence of electronegative elements like oxygen, fluorine, nitrogen.

We know, the electronegativity of oxygen is much more than sulphur atom. So, it is expected that we would find intermolecular hydrogen bonding in water than hydrogen sulphide.

So, due to intermolecular hydrogen bonding, many similar molecules join due to the formation of these strong bonds. As a result of which, a large amount of energy is required to break these bonds. Therefore, boiling point of water is higher than that of hydrogen sulphide.
