Intermolecular Forces Worksheet 2 Answers 1) Using your knowledge of molecular structure, identify the main intermolecular force in the following compounds. Molecules can have any mix of these three kinds of intermolecular forces, but all substances at least have London dispersion forces. Liquids and solids are similar in that they are matter composed of atoms, ions, or molecules. Similarly, if a molecule does not have a dipole moment nor monopole moment, then quadrupolar interactions will be important.
