The crystals formed due to London forces of interaction are:
Correct answer: B. Molecular
- A. lonic
- B. Molecular
- C. Covalent
- D. Metallic
Explanation
Molecular crystals are formed by individual molecules held together by various types of intermolecular forces, including London dispersion forces. The weak London forces play a significant role in the cohesion of molecular crystals, especially in nonpolar molecules.

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.
