Unformatted text preview: Chapter 12. Intermolecular Forces, Liquidsvand Solids. Types of Intermolecular Forces — Section 12.3 We have covalent compounds and ionic compounds. For ionic compounds, the attraction between the ions is due to electrostatic forces as given by Coulomb’s law (page 93). For covalent compounds, those that are actually molecules (_ molecular solids and liquids) the attractive forces between molecules are called. intermolecular forces. These are still electrostatic attractions but are much weaker than forces between oppositely charged ions. Intermolecular forces can be discussed in terms of pure substances and mixtures of substances. Intermolecular forces control solubility, typically “like” dissolves “like”. ‘ Polar molecules are miscible/soluble in otheWs and non-polar molecules are miscible/soluble in other non-polar molecules. This is why water and oil don’t mix, but oil and gasoline do mix. Water and vinegar mix, but vinegar and oil don’t mix. Ethanol and oil only mix to a 10% ethanol solution, above that two phases separate out. For pure substances we have dipole-dipole interactions, London Forces and Hydrogen bonding. For mixtures, we have dipole—dipole interactions, dipole-induced dipole, London Forces and Hydrogen bonding. ...
