- D. Forces that occur only in ionic compounds
Answer
Forces between polar molecules due to their dipoles
Explanation
Permanent dipole-dipole forces occur between polar molecules where there is a permanent separation of charge, leading to attractions between the positive end of one molecule and the negative end of another.
Common mistake
Confusing Dipole-Dipole Forces with Other Intermolecular Forces
Students often confuse permanent dipole-dipole forces with London dispersion forces, failing to recognize that dipole-dipole forces occur between polar molecules due to their permanent dipoles.
To clarify, remember that permanent dipole-dipole forces arise from the attraction between the positive end of one polar molecule and the negative end of another. Review the characteristics of polar molecules and how their dipoles interact.
