What are the properties of simple covalent substances such as chlorine oxygen and water?

The properties of simple covalent substances such as chlorine, oxygen and water are that it has low melting and boiling points. This is because the weak intermolecular forces break down easily. Secondly, another property is the simple covalent substances are non-conductive therefore the substances with a simple molecular structure do not conduct electricity. This is because they do not have any free electrons or an overall electric charge.
