Melting Points of Non-Polar Molecular solids are
Correct answer: B. Low
- A. High
- B. Low
- C. Sharp
- D. None of these
Explanation
Non-polar molecular solids have the weakest form of intermolecular forces - instantaneous dipole-induced dipole forces - which require less energy to overcome hence they have low melting points.

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.
