Why Do Covalent Compounds Have Low Melting and Boiling Points?
BY Team Aakash Byju's
Covalent compounds are chemical substances that are formed by covalent bonds. Covalent compounds have atoms that share one or more pairs of valence electrons.
These compounds are insoluble in water but soluble in organic chemical solutions.
Covalent compounds are commonly made up of neutral chemical molecules.
Covalent compound's melting point and boiling point are commonly low.
The temperature at which a chemical substance changes from a solid to a liquid state.
Melting Point
Boiling Point
The temperature at which a chemical substance vapour pressure equals atmospheric pressure.
Covalent compounds’ melting point and boiling point are commonly low because weak Van der Waals forces hold the molecules together in covalent compounds.
Van der Waals forces are the attraction and repulsion forces between molecules, atoms, surfaces and intermolecular forces.
Hence covalent compounds have a low melting point and low boiling point.
