AQA A Level Chemistry Benzene Structure & Stability (3.3.10)

This fully structured lesson teaches benzene the way examiners expect it to be understood: through evidence.

Students begin with the Kekulé model and test its predictions against real data. They analyse bond lengths (0.140 nm), calculate enthalpy of hydrogenation (−208 vs predicted −360 kJ mol⁻¹), and determine stabilisation energy (152 kJ mol⁻¹). From there, they evaluate why the model fails and build the delocalised π system properly, including lateral p-orbital overlap.

Includes:

• Retrieval starter
• Structured reasoning tasks
• Worked ΔH calculations
• Clear model answers
• Diagnostic questioning
• Consolidation and exam-style review

No filler content. Every slide drives analytical thinking and links explicitly to AQA assessment objectives.

Ideal for Year 13 AQA groups, new teachers wanting a secure structure, or experienced teachers refining conceptual clarity.

Editable PowerPoint. Ready to teach.
