The intermolecular interactions between halogen molecules are Van der Waals' forces. Explain how these Van der Waal's forces arise between halogen molecules.
Electrons are mobile or move in halogen molecules. Therefore, there can be an uneven distribution of electrons or electron density in halogen molecules (1 mark). This creates a temporary or instantaneous dipole or dipole moment in a halogen molecule (1 mark). This subsequently causes an induced dipole moment in neighbouring or surrounding halogen molecules (1 mark).
