Complete Topic 4d: Alkenes Edexcel IGCSE Chemistry 9–1 Bundle 3 lessons

Bundle of 3 fully planned lessons and resources for Topic 4d Alkenes Edexcel IGCSE 9–1 Double/Separate Chemistry.

Checklist, key terms, definitions, tech guide, revision PowerPoint, coursebook questions and answers included. Perfect for new and experienced teachers, this resource provides an authentic, ready-to-teach unit requiring no additional preparation. All lessons are contained in one PowerPoint with a consistent, clear structure.

Lessons & Key Content:

1. Introduction to Alkenes & Unsaturation – general formula (CₙH₂ₙ), presence of a C=C double bond, drawing and naming simple alkenes, comparing saturated vs unsaturated hydrocarbons and their reactivity.

2. Isomers & Addition Reactions (Bromine Test) – drawing structural isomers (e.g., C₄H₈), bromine water test for unsaturation, addition reactions and corresponding word and symbol equations; comparison of alkanes vs alkenes.

3. Cracking & Production of Alkenes – need for cracking due to supply and demand, thermal and catalytic cracking methods, practical demonstration of cracking paraffin, identifying products and testing them with bromine water.

4. End-of-Topic Review – structured revision tasks, organic chemistry recap (alkanes, alkenes, crude oil, cracking), mixed exam-style questions with worked examples.

Each lesson includes starter slides with title, learning goals and tasks, along with key terms, bolded explanations, and content checked against the specification and examination papers. Key demonstrations are included where relevant with step-by-step modelling, notes, diagrams and student tasks. The PowerPoint features click-in animations, embedded video links, model questions and answers, and coursebook tasks to support strong conceptual understanding. A technician guide and full lesson list appear on Slide 2 for easy planning.

Notes:
Slide 1 is repeated for TES display purposes.
Lesson starter slide background is black but PowerPoint colour schemes vary throughout.
Separate Chemistry content is clearly marked and distinguished from Double Award content.
