Sri Lanka GCE A/Level Chemistry
In the molecular world of material transformation, chemistry serves as the central science of innovation. This course invites you to explore the architecture of matter by moving from the fundamental principles of atomic structure to the complex pathways of organic synthesis. You will gain a solid command of stoichiometric and thermodynamic concepts, where you will learn to process experimental data and maintain accurate records of chemical observations. Crucially, you will develop the technical ability to perform qualitative and quantitative analyses while ensuring compliance with laboratory safety and precision. By mastering the analysis and interpretation of reaction mechanisms and industrial processes, you will be equipped to evaluate environmental and technological solutions using scientific reasoning and make sustainable decisions based on chemical evidence.
Core Content Areas
The Sri Lankan GCE A/Level Chemistry syllabus is a comprehensive two-year course covering general, physical, inorganic, organic, and industrial chemistry.
1. Atomic Structure and Bonding
Focuses on quantum numbers, electron configuration, periodic trends, and theories of bonding (VSEPR, hybridization).
2. Chemical Calculations
Explores the mole concept, stoichiometry, gas laws, and concentration calculations essential for quantitative analysis.
3. Physical Chemistry
Covers energetics (Born-Haber cycles), chemical kinetics, gaseous and ionic equilibria, and electrochemistry.
4. Inorganic Chemistry
Investigates the chemistry of s, p, and d block elements, including transition metals and qualitative analysis of ions.
5. Organic Chemistry
Deals with reaction mechanisms and synthesis of hydrocarbons, alkyl halides, alcohols, carbonyls, and nitrogen compounds.
6. Industrial and Environmental Chemistry
Focuses on local Sri Lankan industries (e.g., rubber, essential oils), pollution control, and green chemistry principles.
Assessment Structure
The GCE A/Level Chemistry qualification is assessed by the Department of Examinations via two written papers.
- Paper 1 (Multiple Choice): A 2-hour exam consisting of 50 multiple-choice questions designed to test breadth of knowledge and calculation speed.
- Paper 2 (Structured & Essay): A 3-hour exam. Part A contains 4 compulsory structured essay questions. Part B requires students to answer 4 out of 6 essay questions.
- Practical Component: Practical competency is assessed through written questions in Paper 1 and Paper 2, focusing on experimental design and error analysis.
