Study Notes
- The fundamental difference between states of matter is the strength of intermolecular forces of attraction.
- Physical properties like boiling points, melting points, viscosity, surface tension, and capillary action reflect intermolecular forces.
- Weakest to strongest forces: dispersion forces, dipole-dipole forces, hydrogen bonding, ion-dipole forces.
- Hydrogen bonding arises from the high electronegativity of nitrogen, oxygen, and fluorine.
- Ion-dipole interactions are found in solutions of ions.
- Phase diagrams show melting, boiling, and sublimation points at different pressures.
- Water has a high critical temperature and pressure due to strong van der Waals forces between water molecules.
- Liquid crystals have traits of both solids and liquids.
- Nematic liquid crystals are only ordered in one dimension, while smectic liquid crystals are ordered in two dimensions.
- Cholesteryic liquid crystals have nematic-like crystals layered at angles to each other.
