Question

The low volatility of water as compared to the other hydrides of group 16 elements is due to the ______ of H₂O molecules through ______.

Answer 1

The low volatility of water as compared to the other hydrides of group 16 elements is due to the association of H₂O molecules through intermolecular hydrogen bonding.

Explanation:

Water (H₂O) molecules form strong intermolecular hydrogen bonds, which result in their association. A large amount of energy is required to break these bonds, leading to a higher boiling point and hence low volatility compared to other group 16 hydrides like H₂S, H₂Se, and H₂Te.
