प्रश्न
Some of the properties of water are described below. Which of them is/are not correct?
(i) Water is known to be a universal solvent.
(ii) Hydrogen bonding is present to a large extent in liquid water.
(iii) There is no hydrogen bonding in the frozen state of water.
(iv) Frozen water is heavier than liquid water.
उत्तर
(iii) There is no hydrogen bonding in the frozen state of water.
(iv) Frozen water is heavier than liquid water.
Explanation:
The presence of extensive hydrogen bonding between water molecules gives it remarkable features in the condensed phase (liquid and solid phases). In comparison to \[\ce{H2S}\] and \[\ce{H2Se}\], this results in a high freezing point, high boiling point, high heat of vaporisation, and high heat of fusion.
