In carbon tetrafluoride (CF4), the predominant type of intermolecular force is London dispersion forces, which are a category of van der Waals forces.
CF4 is a nonpolar molecule because the dipole moments of the bonds between carbon and fluorine cancel each other out due to the symmetrical tetrahedral geometry of the molecule. In nonpolar molecules like CF4, London dispersion forces arise from the temporary dipoles that are created when electrons move around the nuclei of the atoms. These temporary dipoles can induce similar dipoles in neighboring molecules, leading to an attractive force between them.
Unlike polar molecules that exhibit stronger dipole-dipole interactions or hydrogen bonding, CF4 relies solely on these temporary attractions to hold the molecules together in a condensed phase. Therefore, while it is a relatively weak intermolecular force, it becomes the dominant one in CF4.
