Chapters

Learning objectives

Trace a property from bonding, shape, polarity, and particle attraction.
Predict boiling point and solubility from intermolecular forces.
Explain conductivity using mobile charged particles.
Compare diamond and graphite using bonding networks.
Relate branching and polymer cross-links to bulk properties.

Core reasoning

Structure determines particle attractions and mobility. Those microscopic causes produce measurable properties such as boiling point, solubility, conductivity, hardness, and flexibility.

Suggested experiments

Heat water and hexane and compare particle escape.
Place ethanol and hexane in water, then oil.
Compare solid salt, salt solution, and sugar solution.
Compare diamond's network with graphite's sliding layers.
Increase polymer cross-links and watch stretching change.

Questions

Why does water boil unusually high? Why can salt solution conduct? Why are diamond and graphite so different although both contain carbon?
