Chemistry Year 12 - Module 8 - Lesson 15
Drug Synthesis & Green Chemistry
1. Key Ideas
Making aspirin in the lab looks simple on paper, but pharmaceutical synthesis is about more than obtaining a product. Chemists also ask how much waste is produced, how efficiently atoms end up in the desired molecule, whether catalysts can improve the route, and how a candidate drug moves from discovery to approval.
- The reagents, conditions and products in aspirin synthesis
- Why green chemistry is about waste prevention, not only yield
2. Success Criteria
By the end, you should be able to:
- The reagents, conditions and products in aspirin synthesis
- The stages of pharmaceutical drug development
- The meanings of atom economy, E-factor and catalyst

5. Short Answer Questions
1. Explain this lesson goal in your own words: "The reagents, conditions and products in aspirin synthesis". Use one specific example from the lesson.
2. Apply this idea to a new example: "The stages of pharmaceutical drug development". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Drug Synthesis & Green Chemistry: "The meanings of atom economy, E-factor and catalyst".
6. Extend: Apply the Idea
A student gives a memorised answer about Drug Synthesis & Green Chemistry but does not use evidence or reasoning.
Improve the answer by writing a stronger response that uses accurate terminology, a relevant example and a clear explanation.
