Complete Topic 4d: Alkenes, Reactions & Cracking Edexcel IGCSE Chemistry 9–1 bundle. 2 Intensive lessons / full teaching (27 slides) & resources

Comprehensive bundle of fully planned lessons and resources covering Alkenes, their reactions, and cracking from the Edexcel IGCSE Chemistry 9–1 specification, suitable for Double Award and Separate Chemistry.

The lessons are fast-paced and content-rich, designed to meet the demands of Separate Chemistry students, while remaining fully accessible for Double Award classes.
This ready-to-teach unit includes lesson PowerPoint(s), revision PowerPoint, learning list, key terms, and exam-focused questions, providing a complete, specification-matched sequence that requires no additional preparation.

Lessons & Key Content (Specification 4.1–4.6, 4.17–4.18, 4.23–4.28)

1. Alkenes: Structure & Formulae
   Functional group >C=C< (4.23); general formula (4.24); alkenes as unsaturated hydrocarbons (4.25); structural and displayed formulae up to four carbon atoms, including unbranched-chain isomers (4.26).
   Reactions of Alkenes
   Reactions with bromine to form dibromoalkanes (4.27); bromine water test to distinguish alkenes from alkanes (4.28); clear modelling and exam-style questions.
2. Cracking of Alkanes
   Conversion of long-chain alkanes into alkenes and shorter-chain alkanes (4.17); reasons for cracking linked to supply and demand for fractions (4.18).
