Web8 apr. 2024 · Three major types of intermolecular forces in liquid are dipole-dipole attractions, London-dispersion forces, and hydrogen bonding. An intermolecular force is an attractive force that develops between the protons or positive parts of one molecule and the electrons or negative parts of another molecule. WebFor example, intermolecular forces can affect the melting and boiling points of a substance, as well as its solubility and viscosity. 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.
