Welcome to Unit 2: Energetics, Group Chemistry, Halogenoalkanes and Alcohols – a crucial module in the Pearson Edexcel International AS Chemistry course. This unit deepens your understanding of chemical energetics, reactivity trends in Groups 2 and 7, and organic functional groups such as alcohols and halogenoalkanes. You will also begin to explore core practicals, redox reactions, and mechanisms in greater detail.
Topics Covered
- Energetics and Enthalpy Changes
- Redox Chemistry and Oxidation Numbers
- Group Chemistry – Trends in Group 2 and Group 7
- Halogenoalkanes – Properties and Mechanisms
- Alcohols – Reactions and Uses
- Core Practicals: Hydrolysis, Chlorination, Redox Titrations
Each topic includes animated video lessons, exam-board-style quizzes, and downloadable PDF summaries. Our resources are updated in line with the official Edexcel IAL Chemistry specification.
Learning Outcomes
- Calculate enthalpy changes using experimental data and Hess's Law
- Describe and explain trends in reactivity across Group 2 and Group 7
- Write ionic half equations and assign oxidation numbers
- Understand nucleophilic substitution and elimination mechanisms
- Describe the physical and chemical behaviour of alcohols and halogenoalkanes
- Interpret the results of core practical experiments
