Answer:

• Covalent compounds usually have low melting points. An exception to this include molecules of silica and diamonds that have a high melting point.
• These compounds have low boiling points. This can be attributed to their weak force of attraction between the various bonded atoms. Van Der Waals forces bind these atoms.
• These compounds are usually gases and liquids with low boiling and melting points.
• The solid covalent compounds have soft structures like graphite. This is because of the presence of a cloud of electrons in between each layer of carbons atoms.
• These compounds are non-conductors of electrical charge. The absence of charged ions is the main reason behind this. An exception to this is graphite, where we see a cloud of electrons. These make graphite a good conductor.
• They are bad conductors of heat also. Their molecules lack free electrons and that obstructs the flow of heat energy.
