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...

Intermolecular forces and how they affect physical properties /purification techniques: dipole-dipole, electrostatic, hydrogen, ion, london, - Answer-*dipole-dipole*: polar covalent molecules such as aldehydes and ketones. positive and negative end. polar molecules must be close together for force to be significant. weaker than ion-dipole forces; increase with polarity of molecule. *electrostatic*: occur between charged species, cations and anions, and are responsible for very high MP and B...
