EEJ MAIN Chemistry QUESTION #7199
Question 1
Identify the incorrect statement regarding the properties of water ($H_{2}O$).
  • Water can exhibit both acidic and basic behavior.
  • Extensive intramolecular hydrogen bonding occurs in the condensed phase.✔️
  • Ice formed from heavy water ($D_{2}O$) will sink in normal water.
  • During photosynthesis, water undergoes oxidation to produce oxygen.
Correct Answer Explanation
  • Statement B is false because water exhibits extensive intermolecular hydrogen bonding, not intramolecular.
  • Intermolecular bonding occurs between different molecules, which is responsible for water's high boiling point and surface tension.
