The types of intermolecular forces that occur in a substance will affect its properties, such as its phase, melting point and boiling point. You should remember from the kinetic theory of matter (see grade 10), that the phase of a substance is determined by how strong the forces are between its particles.imilar to ion-dipole forces these forces exist between ions and non-polar molecules. The ion induces a dipole in the non-polar molecule leading to a weak, short lived force which holds the compounds together. These forces are found in haemoglobin (the molecule that carries oxygen around your body).
