Repulsive and Total Interactions Between Molecules

Intermolecular forces are the repulsive or attractive interaction between the molecules. Due to the coulomb’s law, there will be a coulomb force that exists between two or more charged species. If the charge of both molecules is positive or negative, then that will lead to repulsive forces. When they have opposite charges, then the force is attractive.
