Question

What can you say about the melting point and boiling point of compound Z

Answer 1

Explanation:

Covalent bond have weak intermolecular forces, that is to say, the forces between molecules is very weak. The consequence of this, is that it becomes easy to move individual molecules away from other molecules as the bonding between molecules is weak, hence it needs little energy to break. Since temperature is proportional to energy, that means the temperature required to melt the compound is low.
