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 stronger than intermolecular forces, which are present between atoms or molecules that are not bonded. Types of intramolecular force.
Intermolecular force. Intermolecular forces (IMFs) 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. Inter-molecular forces are weak relative to intramolecular forces â the forces which hold a molecule together. For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules.
