Most molecular crystals melt below?
- 200°C
- 280°C
- 330°C
- 480°C
Explanation
Most molecular crystals melt below 200°C.
Molecular crystals are composed of discrete molecules held together by weak intermolecular forces,
Such as van der Waals forces, dipole-dipole interactions, and hydrogen bonds.
Because these forces are weak, they require relatively little energy to overcome, resulting in low melting and boiling points.
Therefore, their melting points are typically well below 300°C, and often below 200°C, unlike ionic or metallic crystals, which have much stronger bonds and higher melting points
