There are several different types of intermolecular forces, including London dispersion forces, Van Der Waals forces (interactions), ion-dipole, dipole-dipole interactions, and hydrogen bonding. This website uses cookies to improve your experience while you navigate through the website. Instead, the ion generates a transient dipole from a nonpolar molecule by attracting or repelling its electrons. molality of the solution = 0.0125 mol/ 0.0152 Kg = 0.822 Many molecules are polar and can form bipole-bipole bonds without forming hydrogen bonds or even having hydrogen in their molecule. The weigh is proportion to the London dispersion force, and the higher molecular weigh, the larger the force. Potassium chloride is composed of ions, so the intermolecular interaction in potassium chloride is ionic forces. They include Van Der Waals forces (interactions), ion-dipole and dipole-dipole forces.
