Final answer:
The strongest interaction between molecules of F2 is dispersion forces. Other interactions present include covalent bonds, dipole-dipole interactions, and hydrogen bonds.
Step-by-step explanation:
The strongest interaction between molecules of F2 is dispersion forces. Dispersion forces occur as atoms develop temporary dipole moments when their electrons are distributed asymmetrically. This results in rapidly fluctuating, temporary dipoles that attract one another. Other interactions present between F2 molecules include covalent bonds, dipole-dipole interactions, and hydrogen bonds.
