The interaction between intermolecular forces may be used to describe how molecules interact with each other. The strength or weakness of intermolecular forces determines the state of matter of a substance (e.g., solid, liquid, gas) and some of the chemical properties (e.g., melting point, structure). There are three major types of intermolecular forces: London dispersion force, dipole-dipole ...


Intermolecular forces (IMF) are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g., atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together.


\nIn general, intermolecular forces can be divided into several categories. The four prominent types are: \nStrong ionic attraction\nRecall lattice energy and its relations to properties of solid.


Intermolecular forces are weak attractive forces between molecules. There are three types of intermolecular forces. The first one is called London forces, also known as dispersion forces the second one is dipole-dipole interaction and finally, the third one is Hydrogen bonding.


The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.


Three basic intermolecular forces are possible: ion-dipole, dipole-dipole, and London, or dispersion, forces. To unlock this lesson you must be a Study.com Member. Create your account

An intramolecular force is any force that binds together the atoms making up a molecule or compound, not to be confused with intermolecular forces, which are the forces present between molecules. The subtle difference in the name comes from the Latin roots of English with inter meaning between or among and intra meaning inside.


Effect of Intermolecular forces on Melting Points and Boiling Points of Molecular Covalent Substances. Since melting or boiling result from a progressive weakening of the attractive forces between the covalent molecules, the stronger the intermolecular force is, the more energy is required to melt the solid or boil the liquid.


Best Answer: the three main types of intermolecular forces are as follows: 1)instantaneous dipole-induced dipole forces (or van der waals forces): these are bonds formed between the molecules of a substance due to the displacement of the electrons in the molecule.
