Why do most covalent compounds have low melting points?
Aweak inter-molecular forces
Bstrong inter-molecular forces
Chigh lattice energy
Dstrong covalent bonds
Answer & Solution
Correct answer: A. weak inter-molecular forces
Within a molecule, covalent bonds are strong. But the forces *between* molecules are weak, so little energy is needed to separate them — hence low m.p.
