BIO NMDCAT Biological Importance of Water
nmdcat.online June 27, 2026

The fact that water is a liquid at room temperature, unlike other molecules of similar molecular weight (e.g., H₂S, which is a gas), is attributed to

A. The linear geometry of the water molecule
B. The extensive intermolecular hydrogen bonding between water molecules
✓
C. The presence of strong ionic bonds holding water molecules together
D. The low electronegativity of the oxygen atom

📝 Explanation

H₂S cannot form significant hydrogen bonds due to sulfur's lower electronegativity. Water's ability to form a 3D network of strong intermolecular H-bonds requires considerably more thermal energy to separate the molecules into a gaseous state, thus resulting in a liquid state at room temperature.

📖 Additional Information

  • The linear geometry of the water molecule
  • The extensive intermolecular hydrogen bonding between water molecules
  • The presence of strong ionic bonds holding water molecules together
  • The low electronegativity of the oxygen atom
