Intermolecular forces (IMFs) correct answer: the forces of attraction between molecules of covalent compounds (weak) Intramolecular forces correct answer: forces within molecules. Forces caused by the attraction and repulsion of charged particles (strong) Dispersion forces correct answer: present in all molecules attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces; these are the weakest inter...
