Final answer:
The primary intermolecular force that exists between molecules of carbon tetrachloride (CCl4) is London dispersion forces.
Step-by-step explanation:
The primary intermolecular force that exists between molecules of carbon tetrachloride (CCl4) is London dispersion forces.
London dispersion forces, also known as van der Waals forces or induced dipole-dipole forces, occur due to temporary fluctuations in electron distribution around atoms or molecules. Since carbon tetrachloride is a nonpolar molecule, the only intermolecular force acting between its molecules is London dispersion forces.
London dispersion forces are the weakest type of intermolecular force but still play a significant role in determining the physical properties of substances.
