Carbon dioxide is an example of?
Correct answer: C. Molecular Solid
- A. Ionic Solid
- B. Metallic Solid
- C. Molecular Solid
- D. Covalent Solid
Explanation
A molecular solid is composed of molecules held together by van der Waals forces. It is a solid that consists of discrete molecules. All these properties are of CO2 so it is an example of a molecular solid as it has relatively Van Der Waals London Dispersion Forces. Hence, option C is correct.

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.
