← ScienceWhich behavior dictates molecular crystals' low melting points?
A)Weak intermolecular Van der Waals force✓
B)Strong intramolecular covalent bonding
C)High molecular lattice energy
D)Extensive three-dimensional hydrogen bonding
💡 Explanation
Molecular crystals have low melting points because the weak intermolecular Van der Waals force requires little energy to overcome, therefore the solid breaks easily, rather than if having strong bonds such as covalent or metallic.
