Which intermolecular force is common to all polar molecules but NOT nonpolar molecules?

Question

Quizplus · Accepted Answer

Dipole-dipole forces are common to all polar molecules but not to nonpolar molecules. This is because polar molecules have a permanent dipole moment due to the uneven distribution of electrons, which leads to attractions between the positive end of one molecule and the negative end of another. Nonpolar molecules do not have a permanent dipole moment and thus do not exhibit dipole-dipole interactions.
