Intramolecular force


An intramolecular force is any force that holds together the atoms making up a molecule or compound. They contain all types of chemical bonds. They are usually stronger than intermolecular forces, which are present between atoms or molecules that are not bonded. Hydrogen bonds are an important case of forces than can be either intramolecular or intermolecular.

There are several types of intramolecular forces, distinguished by the types of constituent atoms and the behavior of electrons. These are the main ones.

They differ in the magnitude of their bond enthalpies, a measure of bond strength, and thus affect the physical and chemical properties of compounds in different ways.
