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 (20% overall), assessing Planning (15% within Paper 3) and MMO/PDO/ACE (85%) - with a printed Notes for Qualitative Analysis available at the bench (same source).
Master the mole concept, acid-base salt prep, and qualitative-analysis observations early so Paper 3 routines fit comfortably within the 1 h 50 min window.

Status: SEAB O-Level Chemistry syllabus 6092 (first exam 2026) checked 2026-05-08 - refresh when SEAB publishes a newer syllabus edition.

IP students: if you’re using O-Level topics to shore up Year 3-4 fundamentals, start with our IP Chemistry tuition hub and IP Chemistry Upper Sec Notes hub.

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, % yield, % 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
