Which one of the following statements about water is FALSE ? (1) Water is oxidized to oxygen during photosynthesis (2) Water can act both as an acid and as a base (3) There is extensive intramolecular hydrogen bonding in the condensed phase (4) Ice formed by heavy water sinks in normal water

1. Water is oxidized to oxygen during photosynthesis
2. Water can act both as an acid and as a base
3. There is extensive intramolecular hydrogen bonding in the condensed phase
4. Ice formed by heavy water sinks in normal water

Correct answer: There is extensive intramolecular hydrogen bonding in the condensed phase

Solution

The statement about extensive intramolecular hydrogen bonding in the condensed phase is incorrect because water primarily exhibits intermolecular hydrogen bonding, which is crucial for its unique properties, rather than significant intramolecular bonding.
