Answer:
<em>intermolecular forces and intramolecular forces</em>
Explanation:
Intermolecular forces can be described as the forces that are present between molecule or compounds.
Intramolecular forces are forces which are present within a compound or molecule.
For example, consider HCl which is made of hydrogen and chlorine atoms. The forces which will be present between the molecules of HCl will be called as intermolecular forces. The forces which will be present between hydrogen and chlorine will be termed as intramolecular forces.
