Question 3
If there were no intermolecular bonds between water molecules, what would water be like at room temperature?
The right answer is the one marked above.
It would be a gas at room temperature. Water is a small, light molecule; only the attractions between its molecules hold it together as a liquid.
Removing an attraction cannot make a substance freeze — freezing needs molecules held more firmly, not less. Decomposition would require the covalent bonds inside the molecule to break, which is a different matter entirely.
