Teach the concept first, then use the worked example as a model for AP-style explanations. • For free-response questions, connect observations to electrostatic attraction, molecular geometry, electron distribution, or intermolecular forces. • Do not rely on memorized labels alone; AP questions often ask for a particulate-level explanation.
