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.
Hydrogen bonds tend to be the strongest type of intermolecular force. None of these intermolecular forces, however, is as strong as ordinary ionic or covalent bonds. Figure 11.12 presents a systematic way of identifying the kinds of intermolecular forces in a particular system, including ion-dipole and ion-ion forces.
