The Physical Properties and Trends of Organic Compounds
This post will be an introduction to physical properties and trends for QCE Chemistry.
4.1.2 – Physical Properties and Trends
- Recognise that organic compounds display characteristic physical properties, including melting point, boiling point and solubility in water and organic solvents that can be explained in terms of intermolecular forces (dispersion forces, dipole-dipole interactions and hydrogen bonds), which are influenced by the nature of the functional groups
- Predict and explain the trends in melting and boiling point for members of a homologous series
Intermolecular Forces
This video introduces the different types of intermolecular forces.
This video looks at the relationship between bond strength and bond length.
Boiling Points and Melting Points
This video explores the relationship of boiling point and intermolecular bonding.
This video looks at melting and boiling point trends.
This is a practice problem around explaining the trends of the boiling point.
Solubility
This video looks at the relationship between solubility and intermolecular forces.
This video looks specifically at the solubility of organic compounds.
