Chemistry Year 12 - Module 8 - Lesson 11
Drug Classification & Functional Groups
1. Key Ideas
Ibuprofen tablets are commonly sold in 200 mg doses, while paracetamol tablets are often 500 mg. That difference is not random. In medicinal chemistry, structure influences binding, potency, solubility and the way a molecule behaves in the body.
- The main structural and functional medicine categories named in the course
- How functional groups influence polarity, solubility, reactivity and binding
2. Success Criteria
By the end, you should be able to:
- The main structural and functional medicine categories named in the course
- The key functional groups found in common drug molecules
- The meaning of the term pharmacophore
3. Key Terms

5. Short Answer Questions
1. Explain this lesson goal in your own words: "The main structural and functional medicine categories named in the course". Use one specific example from the lesson.
2. Apply this idea to a new example: "The key functional groups found in common drug molecules". Show your reasoning clearly.
3. Analyse why this idea matters for understanding Drug Classification & Functional Groups: "The meaning of the term pharmacophore".
6. Extend: Apply the Idea
A student gives a memorised answer about Drug Classification & Functional Groups 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.
