Question

which statement describes a property of covalent compounds?
they have a high boiling point because of strong intermolecular forces.
they have a low boiling point because of weak intermolecular forces.
they have a low melting point because of strong intermolecular forces.
they have a high melting point because of weak intermolecular forces.

Explanation:

Covalent compounds have weak intermolecular forces. Melting and boiling points are related to the strength of these forces. Stronger forces require more energy (higher temperature) to overcome. Since covalent compounds have weak intermolecular forces, less energy is needed to change their state (from solid - liquid - gas). So, they have low melting and boiling points.

Answer:

They have a low boiling point because of weak intermolecular forces.
