Problem 9 : Explain the formation of hydrogen bonds between water molecules. Discuss how hydrogen bonding influences the unique properties of water.
Solution :
Hydrogen bonds in water form due to the attraction between the partially positive hydrogen atom (from one water molecule) and the partially negative oxygen atom (from another water molecule). Hydrogen bonding in water leads to several unique properties, including:
- High boiling point and melting point due to strong intermolecular forces.
- High specific heat capacity, which stabilizes temperatures in aquatic ecosystems.
- Surface tension, allowing insects to “walk” on water.
- Expansion upon freezing, making ice less dense than liquid water.
These properties are crucial for the existence of life on Earth.
