Boiling Points of Polar Molecular solids are
Correct answer: C. High
- A. Low
- B. Moderate
- C. High
- D. Cannot be predicted
Explanation
Polar molecules have permanent dipoles resulting in strong intermolecular forces of attraction- permanent dipole-permanent dipole forces- which require a lot of energy to be overcome hence the boiling points are high as well.

About Ionic and Molecular Crystals
Ionic crystals contain oppositely charged ions held by electrostatic forces, whereas molecular crystals contain discrete molecules joined by weaker intermolecular forces. Their structures explain differences in melting point, hardness, volatility, solubility and electrical conductivity, especially between solid and molten states.
