What type of intermolecular forces arise between halogen molecules? Explain how they arise.
London dispersion forces. These arise because: 1. Electrons within the halogen molecule are constantly moving and at any one instant there is an uneven distribution of electrons within the molecule. 2. This causes there to be an instanteous dipole. This will induce dipoles in neighbouring molecules. 3. There is an electrostatic force of attraction between molecules due to the dipoles.
