Q: What does O-Level Chemistry Syllabus: 2026 Edition (Singapore) cover?
A: A parent- and student-friendly roadmap to the SEAB 6092 O-Level Chemistry specification - exam format, the twelve topics across three sections, Paper 3 practical skills, and the printed Notes for Qualitative Analysis.

TL;DR
The 2026 SEAB 6092 Chemistry spec organises content into 12 topics across three sections - Matter (1-3), Chemical Reactions (4-10), and Chemistry in a Sustainable World (11-12) (SEAB syllabus PDF).
Paper 3 (Practical) runs 1 h 50 min for 40 marks (twenty percent overall), assessing Planning (fifteen percent within Paper 3) and MMO/PDO/ACE (eighty-five percent) - with a printed Notes for Qualitative Analysis available at the bench (same source).
Master Topic 4 chemical calculations early - mole ratios, empirical formulae, solution concentration, yield, purity, and limiting reactants - because the same working discipline carries into Paper 2 structured questions and Paper 3 titration processing.

Status: SEAB O-Level Chemistry syllabus 6092 (first exam 2026) checked 2026-06-02 - refresh when SEAB publishes a newer syllabus edition.

IP students: if you are using O-Level topics to shore up Year 3-4 fundamentals, start with our IP Chemistry tuition hub and Upper Sec Chemistry Notes hub. The notes hub is named for IP because it also serves non-O-Level students, but the topic notes below are aligned to the 6092 upper-secondary Chemistry core.

Paper 1 MCQ	1 h / 40 x 1	30 %	Breadth recall; the Periodic Table is printed in the paper
Paper 2 Structured + Free Response	1 h 45 / 80 m	50 %	Section A (70 m, structured; last two questions worth 20 m incl. one data-based question of 8-12 m); Section B (10 m, choose 1 of 2)
Paper 3 Practical	1 h 50 / 40 m	20 %	Variable number of compulsory practical questions; Planning may be embedded; PDO/ACE may include data-analysis without apparatus

Topic	Core ideas	Anchor formula / fact
1. Experimental Chemistry	Apparatus selection, separation methods, paper chromatography, melting/boiling-point purity	$R_f = \frac{\text{solute distance}}{\text{solvent distance}}$
2. Particulate Nature of Matter	Kinetic particle theory, diffusion, atomic structure, isotopes (Brownian motion not required)	nuclide notation $^{12}_{6}\text{C}$
3. Chemical Bonding and Structure	Ionic, covalent, metallic; dot-and-cross diagrams; simple molecular vs giant covalent (diamond, graphite); alloys	bonding type → physical properties
4. Chemical Calculations	Equations with state symbols, mole concept, Avogadro constant, empirical and molecular formulae, limiting reactants, percentage yield, percentage purity	$n = \frac{m}{M_r}, \quad c = \frac{n}{V}$
5. Acid-Base Chemistry	Acids/alkalis, Universal Indicator, pH, neutralisation, salt prep, Haber Process (Le Chatelier not required)	$\text{H}^+ + \text{OH}^- \rightarrow \text{H}_2\text{O}$
6. Qualitative Analysis	Cation, anion and gas tests	reagent → observation tables (printed in the practical paper)
7. Redox Chemistry	O / H / electron / oxidation-state definitions; KI and KMnO₄ as test reagents; electrolysis with selective discharge; simple cells; H₂ fuel cell	OIL RIG; selective discharge of cations and anions
8. Patterns in the Periodic Table	Periodic trends; Groups 1, 17, 18; transition elements; reactivity series; corrosion + sacrificial protection	reactivity series order (K → Ag)
9. Chemical Energetics	Exothermic ( $\Delta H$ negative) vs endothermic ( $\Delta H$ positive); energy profile diagrams; bond breaking endo / making exo	$\Delta H = \sum E_{\text{broken}} - \sum E_{\text{formed}}$
10. Rate of Reactions	Effect of concentration, pressure, particle size, temperature, catalyst (incl. enzymes); collision theory + activation energy	rate ↔ collision frequency / activation energy
11. Organic Chemistry	Crude oil + bioethanol; alkanes $\text{C}_n\text{H}_{2n+2}$ ; alkenes $\text{C}_n\text{H}_{2n}$
12. Maintaining Air Quality	Dry-air composition (78% N₂ / 21% O₂); pollutants (CO, CH₄, NOₓ, O₃, SO₂); catalytic converters; CaCO₃ for SO₂ capture; ozone layer; carbon cycle; greenhouse gases	pollutant → source → mitigation
