We know that stronger intermolecular forces lead to higher melting points. We also know that oxygen has weaker intermolecular forces than hydrogen chloride (induced dipole versus dipole-dipole forces). Therefore oxygen will have a lower melting point than hydrogen chloride since oxygen has weaker intermolecular forces.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).
