Limiting reagents Study guides, Revision notes & Summaries

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...
