Which one has strongest intermolecular force between I2 and N2?

Iodine (I2) has stronger intermolecular forces compared to nitrogen (N2) due to its larger molecular size and greater polarizability, which enhance London dispersion forces. While both I2 and N2 are nonpolar molecules, the dispersion forces in I2 are significantly stronger because it has more electrons and a larger electron cloud. Consequently, I2 exhibits higher boiling and melting points than N2, indicating stronger intermolecular interactions.
