Which one of the following statements about water is false?

Options

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

Correct answer

D. There is extensive intramolecular hydrogen bonding in the condensed phase

Step-by-step solution

(i) Ice formed by heavy water sinks in normal water due to higher density of D 2 O than normal water (ii) 6 C O 2 + 6 H 2 O → h v c h l o r o p h y l l C 6 H 12 O 6 + 6 O 2 (iii) Water can show amphiprotic nature and hence water can act both as an acid a base (iv) There is extensive intermolecular hydrogen bonding in the condensed phase instead of intramolecular H-bonding
