Question

Quizplus · Accepted Answer

Octane is an organic molecule, which means it is composed mainly of carbon and hydrogen atoms. As a nonpolar molecule, octane experiences London dispersion forces, the dominant intermolecular force of attraction for nonpolar molecules. Dipole-dipole forces are not present as there are no permanent dipoles, and hydrogen bonding and covalent bonds are not intermolecular forces.
