Answer

Explanation:

Step1: Identify intermolecular forces

Carbon - tetrafluoride ($CF_4$) is a non - polar molecule. Non - polar molecules have London dispersion forces as their main intermolecular forces. Dipole - dipole forces occur in polar molecules, so we can rule out the dipole - dipole options.

Step2: Relate London dispersion forces to number of electrons

London dispersion forces are proportional to the number of electrons in a molecule. A molecule with fewer electrons has weaker London dispersion forces. Since $CF_4$ has a lower boiling point than $Br_2$, it has weaker London dispersion forces, which means it has fewer electrons.

Answer:

London Dispersion, fewer
