Lesson Plan

• Describe the classification and key physical properties of primary, secondary, tertiary and aromatic amines.
• Explain trends in basicity of amines and the structural factors that influence them.
• Predict the products of the main amine reactions (alkylation, acylation, Gabriel synthesis, Hofmann elimination, oxidation, diazotisation).
• Apply this knowledge to solve typical A‑Level exam questions involving mechanisms and product identification.

• Projector and screen
• Whiteboard and markers
• Handout of amine classification table
• Worksheet with reaction‑prediction tasks
• Molecular model kits (optional)
• Lab demonstration set‑up (small quantities of an amine, alkyl halide, acid chloride, safety goggles)

Begin with a quick “fishy‑smell” anecdote to capture interest and link to students’ prior knowledge of nitrogen‑containing compounds. Review the concept of basicity and remind learners of the difference between functional groups such as alcohols and amines. State that by the end of the lesson they will be able to classify amines, explain their properties and reliably predict the outcomes of the major reactions covered.

1. Do‑Now (5') – short quiz on nitrogen functional groups and basic definitions.
2. Mini‑lecture (10') – classification, physical properties and basicity trends of amines.
3. Interactive matching activity (10') – students pair reactions with correct amine type/product on a board.
4. Demonstration (15') – safe alkylation of a primary amine; discuss over‑alkylation and mechanism.
5. Guided practice (15') – worksheet covering acylation, Gabriel synthesis, Hofmann elimination, oxidation and diazotisation; teacher circulates for support.
6. Check for understanding (5') – exit‑ticket: write one balanced equation for a chosen amine reaction and note a key condition.

Summarise the classification hierarchy, the basicity trends and the seven hallmark reactions of amines. Collect exit‑tickets to gauge immediate understanding and assign homework: complete a set of A‑Level style questions that require drawing mechanisms and predicting products for each reaction type.
