Study Notes
Intermolecular Forces and Interfacial Phenomena
- Permanent dipoles in polar molecules can induce an electrical dipole in non-polar molecules, which are easily polarized
- Intermolecular forces are responsible for various interfacial phenomena, including:
- Flocculation in suspensions
- Stabilization of emulsions
- Compaction of powders in capsules and tablets
- Compression of granules to form tablets
Types of Intermolecular Forces
- There are three main types of intermolecular forces:
- Van der Waals forces
- Dispersion forces (or London forces)
- Hydrogen bonding
Van der Waals Forces (Dipole-Dipole Forces)
- Occur between molecules with permanent net dipoles (polar molecules)
- Examples: dipole-dipole interactions between H2S molecules
- Characteristics:
- Liquids occupy a definite volume
- Solids have a high degree of order, hardly influenced by thermal motions
Physical Pharmacy and States of Matter
- Solutions can be classified according to the states in which the solute and solvent occur
- Solid State: intermolecular forces are strong, resulting in a high degree of order
