Complete Topic 4c: Alkanes, Isomers & Combustion Edexcel IGCSE Chemistry 9–1 Bundle 5 lessons

Bundle of 5 fully planned lessons and resources for Topic 4c Alkanes, Isomers, Substitution & Combustion 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. Alkanes & Homologous Series – general formula (CₙH₂ₙ₊₂), saturated hydrocarbons, drawing structural/displayed/molecular formulae for the first five alkanes; trends in boiling point explained by intermolecular forces.

2. Isomers & Substitution Reactions – defining structural isomers; drawing isomers of butane and pentane; substitution of alkanes with bromine in UV light; word and symbol equations; bromine decolourisation with alkanes vs alkenes (comparison).

3. Complete vs Incomplete Combustion – products formed (CO₂ + H₂O vs CO/soot); flame colour and energy release differences; writing balanced combustion equations; dangers of carbon monoxide.

4. Environmental Problems of Combustion – greenhouse gases, global warming, formation of sulfur dioxide and nitrogen oxides; causes and effects of acid rain; emission reduction methods (scrubbers, catalytic converters).

5. Acid Rain Display Practical – modelling acid rain, observing effects, and producing display materials summarising causes, consequences and solutions.

6. Revision Lesson – chapter questions, retrieval activities, exam-style practice and Blooket revision links

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. Core practicals or key demonstrations are included where relevant with step-by-step modelling, notes, diagrams and student tasks, blooket and quizzes. 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.
