Chemistry
Matter. Structure. Transformation.
Our Chemistry programme is fully aligned with the MOE H1 Chemistry Syllabus (8873) and the new H2 Chemistry Syllabus (9476) (first examined 2026), building rigorous conceptual understanding and examination precision for A-Level success.
All content is aligned with the requirements set out in the H1 Chemistry Syllabus (8873) and the H2 Chemistry Syllabus (9476) published by the Ministry of Education Singapore.
Which Chemistry Are You Taking?
H2 is the full programme for science-track students; H1 is a complementary science option with a focused syllabus and no practical paper.
Most Common
Syllabus 9476
For science-track students pursuing chemistry-related disciplines
H2 Chemistry (Syllabus 9476, first examined 2026) provides a comprehensive treatment of chemical principles organised around three Core Ideas — Matter, Structure & Properties, and Transformation — and extends into Organic Chemistry, Electrochemistry, and the Chemistry of Transition Elements. The syllabus places greater emphasis on conceptual understanding and the application of scientific principles than on factual recall, and includes a compulsory Practical Paper. It is designed for students intending to pursue university courses in chemistry, medicine, pharmacy, chemical engineering, or the biological sciences.
Our coaching covers all four skill areas — Planning, Manipulation & Observation, Presentation of Data, and Analysis & Evaluation — to prepare students fully for the practical examination.
Nucleus (neutrons, protons, isotopes, proton and nucleon numbers); electrons (electronic energy levels, ionisation energies, atomic orbitals s/p/d, extranuclear structure)
Ionic, covalent, metallic and co-ordinate (dative covalent) bonding; VSEPR shapes and bond angles; bond polarities; intermolecular forces including hydrogen bonding; bond energies and bond lengths; lattice structures of solids; bonding and physical properties
Ideal gas behaviour and deviations; pV = nRT and its use in determining Mr; Dalton's Law for partial pressures in a gas mixture
Arrhenius, Brønsted–Lowry and Lewis theories of acids and bases; conjugate acid-base pairs; Lewis acid-base reactions (e.g. BF₃ and NH₃)
Periodicity of atomic and physical properties across Period 3 (Na–Cl) and down Group 2 and Group 17; periodicity of chemical properties (Period 3 oxides and chlorides; Group 2 reducing agents; Group 17 oxidising agents; thermal stability of Group 2 carbonates and Group 17 hydrides)
Nucleus (neutrons, protons, isotopes, proton and nucleon numbers); electrons (electronic energy levels, ionisation energies, atomic orbitals s/p/d, extranuclear structure)
Enthalpy changes (ΔH); Hess's Law; Born–Haber cycles; entropy changes (ΔS); Gibbs free energy (ΔG) and feasibility of reactions
Rate of reaction; rate equations and order of reaction; Arrhenius equation; collision theory; factors affecting rate; reaction mechanisms; Maxwell-Boltzmann distribution graph
Dynamic equilibrium; equilibrium constant K; Le Chatelier's principle; factors affecting position of equilibrium
Acid/base dissociation constants (Ka, Kb); ionic product of water (Kw); pH calculations; buffer solutions; solubility product (Ksp); common ion effect
Nomenclature, shapes and functional groups; constitutional and stereoisomerism; organic reaction mechanisms (free-radical substitution, electrophilic addition, electrophilic substitution, nucleophilic addition, nucleophilic substitution); functional group reactions of alkanes, alkenes, arenes, halogenoalkanes, halogenoarenes, alcohols, phenols, aldehydes, ketones, carboxylic acids, acyl chlorides, esters, amines, amides, amino acids and nitriles
Standard electrode (redox) potentials and their interpretation; batteries and fuel cells; factors affecting electrolysis; the Faraday constant; industrial applications of electrolysis
General physical and characteristic chemical properties of first-row transition elements Sc to Zn; colour of complexes
Assessment Format
H2 Chemistry (9476) is assessed via four papers. Paper 4 is a compulsory practical examination worth 20% of the total mark.
Paper 1
1 hour
30 compulsory multiple choice questions (MCQ), including 5–8 multiple completion items. All questions include 4 options. Tests knowledge and understanding across the full syllabus.
Paper 2
2 hours
Structured questions including data-based questions (20–25 marks). All questions are compulsory and answered on the question paper. Tests application, analysis and evaluation of chemical data.
Paper 3
2 hours
Section A: 3–4 compulsory structured questions (55 marks). Section B: Answer 1 of 2 questions (20 marks each). Requires integration of knowledge and understanding from different areas of the syllabus.
Paper 4 (Practical)
2 hours 30 min
Practical examination assessing Planning (P, 4%), Manipulation & Measurement & Observation (MMO), Presentation of Data & Observations (PDO), and Analysis, Conclusions & Evaluation (ACE). MMO, PDO and ACE together account for 16%.
Complementary Science
Syllabus 9476
For students taking Chemistry as a contrasting science or breadth subject
H1 Chemistry covers the same three Core Ideas as H2 but at a reduced depth and breadth, with an Extension Topic on Polymers and Organic Chemistry. It is suitable for students who need Chemistry as a supporting science alongside another H2 science, or for those who wish to maintain scientific literacy without committing to the full H2 programme.
H1 Chemistry does not include the Gaseous State, Chemistry of Aqueous Solutions, Electrochemistry, or Transition Elements. There is also no practical paper (Paper 4) for H1.
Electronic structure, ionisation energies, s and p orbitals, electronic configuration
Ionic, covalent, metallic bonding; VSEPR; intermolecular forces; structures and properties
Brønsted–Lowry theory, conjugate acid-base pairs, strength of acids and bases
Periodicity of physical and chemical properties; Period 3 elements; Group 2 and Group 17 trends
Mole calculations, empirical and molecular formulae, stoichiometric calculations
Enthalpy changes; Hess's Law; bond energies; Born–Haber cycles (introductory)
Factors affecting rate of reaction; collision theory; activation energy; catalysis
Dynamic equilibrium; equilibrium constant Kc; Le Chatelier's principle
Functional groups; addition and condensation polymers; proteins; plastics; applications of organic chemistry in materials and sustainability
Assessment Format
H1 Chemistry is assessed via two written papers. There is no practical paper for H1.
Paper 1
1 hour
30 compulsory multiple choice questions (MCQ), including 4–6 multiple completion items. Tests knowledge and understanding across the full H1 syllabus.
Paper 2
2 hours
Section A: Structured questions including data-based questions (60 marks, all compulsory, 15–20 marks data-based). Section B: Answer 1 of 2 free-response questions (20 marks). Requires integration across topics.
How We Coach at Each Stage
Our coaching adapts to where your child is in the JC journey — building chemical foundations in JC1 and refining for peak performance in JC2.
JC2 completes the syllabus with the Extension Topic on Polymers and Organic Chemistry, then pivots to intensive examination preparation. The data-based question in Paper 2 is a key differentiator — our coaching trains students to extract chemical information from unfamiliar contexts and write precise, mark-scheme-aligned answers.
JC1 covers the three Core Ideas, which form the foundation of the H1 Chemistry syllabus. The content builds directly on O-Level Chemistry but with greater rigour — particularly in atomic structure, bonding, and energetics. Our coaching ensures students develop a solid conceptual understanding before moving to examination technique.
Whether your child is taking H1 or H2, our specialist Chemistry coaches provide the conceptual depth, practical skills, and examination precision needed for A-Level success.
