- Year 1 (AS)
- 3 lessons
- Exam practice and flashcards
- LESSON 1Structure, Bonding and Reactivity
Unsaturated hydrocarbons, sigma and pi bonds, stereoisomerism (E/Z isomerism), and structural representations.
- LESSON 2Electrophilic Addition
Mechanisms with HBr, Br2, H2SO4, Markovnikov's rule based on carbocation stability, and direct steam hydration.
- LESSON 3Alkene Tests and Polymers
Testing for unsaturation with bromine water, addition polymerisation mechanisms, and the environmental impacts of plastic waste.
