Question

____ compounds have low melting points and boiling points.

Answer 1

Covalent compounds:

1. Covalent compounds are formed from the weak intermolecular forces of attraction.
2. Covalent bonds are weaker than ionic bonds, so they require less energy to break.
3. Since lower heat (energy) is needed to break these intermolecular forces.
4. Thus, their melting and boiling points are lower.

Therefore, covalent compounds have low melting points and boiling points.
