in the figure below, two nonpolar molecules are interacting.
which interaction would most likely cause these molecules to repel each other?
hydrogen bonding
dipole-dipole interaction
dipole-induced dipole interaction
induced dipole-induced dipole interaction

Explanation:

• Hydrogen bonding only occurs between molecules with H bonded to N/O/F, not nonpolar molecules.
• Dipole-dipole interactions require permanent dipoles, which nonpolar molecules lack.
• Dipole-induced dipole interactions need one molecule with a permanent dipole, which is not the case here.
• Induced dipole-induced dipole (London dispersion) forces can lead to temporary repulsion when electron clouds of nonpolar molecules overlap and repel each other, as the temporary dipoles can align to create repulsive forces.

Answer:

induced dipole-induced dipole interaction
