What is the strongest IMF in Cl2?

In Cl2 (chlorine gas), the strongest intermolecular force (IMF) is London dispersion forces, which are a type of van der Waals force. These forces arise due to temporary dipoles created when the electron distribution around the chlorine molecules fluctuates. Although Cl2 is nonpolar, the presence of these temporary dipoles allows for weak attractions between molecules. Overall, London dispersion forces are the only significant IMFs present in Cl2.
