The official JAMB syllabus for Chemistry 2027 contains exactly 18 topics, starting with separation of mixtures and ending with chemistry and industry. It is published by the Joint Admissions and Matriculation Board for UTME and Direct Entry candidates, it tells you precisely what can appear in the exam, and you can download the PDF free at the bottom of this page or from jamb.gov.ng.
One correction before anything else, because it matters. Plenty of sites circulate a “JAMB Chemistry area of concentration” with 20 or 22 topics. Those lists are the real syllabus chopped up and double-counted: “Acids, bases and salts” split into two entries, “Radioactivity” listed separately when it lives inside atomic structure, and so on. Study from one of those and you will revise some material twice while trusting a list that was never checked against the source. The document JAMB actually publishes has 18 topics, and every one of them is broken down below.

What the syllabus is actually for
The syllabus is the boundary of the exam. JAMB commits to setting questions only from what is on this list, which cuts both ways: nothing outside it can appear, and everything inside it is fair game. It will not teach you anything by itself, and it predicts nothing, but it tells you exactly where the walls are.
That makes it the single most useful document in your preparation, and also the most commonly skipped one. Candidates study from textbooks cover to cover, which wastes weeks on material JAMB never tests, or they study from past questions alone, which leaves gaps wherever a topic happens not to have appeared recently. The syllabus is how you avoid both mistakes. Print it, and tick topics off as you genuinely master them, not as you read them.
JAMB states four overall aims for the Chemistry paper: testing whether you understand basic principles and concepts, whether you can interpret scientific data, whether you can connect chemistry to the other sciences, and whether you can apply it to industry and daily life. Notice how many exam questions are written to those last two aims. JAMB loves the question that dresses a principle in everyday clothing, like why food cooks faster in a pressure cooker or what harmattan haze is, chemically speaking. If your revision never leaves the abstract, those questions will feel unfamiliar even when you know the underlying chemistry cold.

Topic 1: Separation of mixtures and purification
Covers pure versus impure substances, boiling and melting points as purity tests, the difference between elements, compounds and mixtures, chemical versus physical changes, and the full toolkit of separation methods: evaporation, simple and fractional distillation, sublimation, filtration, crystallization, paper and column chromatography, magnetization and decantation.
The exam angle here is matching method to mixture. Given salt in water, iodine mixed with sand, or a dye, you should be able to name the right technique and the principle behind it. Questions also like the everyday application: how gin is distilled from palm wine turns up under organic chemistry too.
Topic 2: Chemical combination
Stoichiometry and the foundational laws: definite and multiple proportions, conservation of matter, Gay-Lussac’s law of combining volumes and Avogadro’s law. Also chemical symbols, formulae and equations, relative atomic mass on the carbon-12 scale, the mole concept and Avogadro’s number.
This is a calculation topic, and it underwrites half the paper. Mole-concept arithmetic shows up inside acids and bases, electrolysis and organic chemistry, so weakness here leaks everywhere. Practise until converting between mass, moles and number of particles is automatic.
Topic 3: Kinetic theory of matter and gas laws
The kinetic theory explanation of melting, boiling, freezing, vaporization and condensation, plus Brownian motion. Then the gas laws: Boyle, Charles, Graham and Dalton’s law of partial pressures, the combined gas law, molar volume, atomicity, and the ideal gas equation PV = nRT, along with the link between vapour density and relative molecular mass.
Expect calculations and graph interpretation. JAMB frequently shows you a pressure-volume or volume-temperature graph and asks which law it represents, so know the shapes as well as the formulas.
Topic 4: Atomic structure and bonding
The heavyweight topic. It covers the atomic models and the scientists behind them (Dalton, Thomson, Millikan, Rutherford, Moseley, Bohr), electron configuration for elements 1 to 20, isotopes, and the shapes of s and p orbitals. The periodic table sits here too, with its trends in ionization energy, ionic radii, electron affinity and electronegativity. So does bonding in all its forms: electrovalent, covalent, coordinate (with complex ions like [Cu(NH3)4]2+ as examples), hydrogen bonding, metallic bonding and van der Waals forces, along with molecular shapes from linear through tetrahedral and pyramidal. Nuclear chemistry rounds it out: types and properties of radiation, nuclear equations, half-life calculations and the applications of radioactivity.
That is an enormous amount of content for one syllabus entry, which is exactly why the inflated 22-topic lists split it apart. Give it the time of two or three ordinary topics. Half-life calculations and electron configuration questions are near-certainties on any paper.
Topic 5: Air
Short and friendly. The gaseous composition of air (nitrogen, oxygen, water vapour, carbon(IV) oxide, argon, neon), why air is a mixture rather than a compound, and the uses of the noble gases. Easy marks for an evening’s work.
Topic 6: Water
Water as a combustion product of hydrogen, water as a solvent, dissolved gases and their biological significance, hard and soft water with the causes and cures of temporary and permanent hardness, town water treatment, and the family of moisture behaviours: water of crystallization, efflorescence, deliquescence and hygroscopy, with examples of each.
The hardness questions are dependable: what causes temporary hardness, why boiling removes it, and why washing soda softens water are classics.
Topic 7: Solubility
Unsaturated, saturated and supersaturated solutions, solubility expressed in moles per dm3, solubility curves and calculations from them, solvents for fats, oils and paints, and false solutions: suspensions and colloids, with local examples the syllabus names directly, harmattan haze as a suspension, fog and emulsion paint as colloids.
Learn to read a solubility curve properly. JAMB asks how much solute crystallizes out when a solution cools from one temperature to another, and that is pure curve-reading plus subtraction.
Topic 8: Environmental pollution
Air pollutants (H2S, CO, SO2, oxides of nitrogen, CFCs, dust), water pollution from sewage and oil, soil pollution and oil spillage, and the difference between biodegradable and non-biodegradable pollutants.
The examples are deliberately Nigerian, the whole topic is passable in an afternoon, and it has been turning up more often in recent papers than its size suggests.
Topic 9: Acids, bases and salts
Properties and definitions, including the H3O+ and proton-donor definitions of an acid, basicity, the four salt types (normal, acidic, basic, double), naturally occurring organic acids like ethanoic, citric and tartaric, salt preparation by neutralization and precipitation, conductance of strong versus weak acids, the pH and pOH scales with calculations, titrations, and hydrolysis of salts such as NH4Cl, AlCl3, Na2CO3 and CH3COONa.
Titration calculations are as close to guaranteed as UTME questions get. So is predicting whether a salt solution is acidic, basic or neutral from its parent acid and base.
Topic 10: Oxidation and reduction
The four ways of defining redox: oxygen gained or lost, hydrogen lost or gained, electrons transferred, and oxidation number changed. Balancing redox equations, IUPAC naming using oxidation numbers, and tests for oxidizing and reducing agents.
Master oxidation numbers and this topic becomes mechanical. They also feed directly into electrolysis and the naming conventions used across the inorganic topics.
Topic 11: Electrolysis
Electrolytes versus non-electrolytes, Faraday’s laws with calculations treating a faraday as a mole of electrons, the classic electrolysis cases (dilute H2SO4, CuSO4 solution, dilute and concentrated NaCl, fused NaCl), factors deciding which ion is discharged, industrial uses including copper purification and aluminium production, electrochemical cells and the redox series, electrode potential calculations, and corrosion with its prevention methods.
Know the electrode products for each classic case by heart. The concentrated-versus-dilute NaCl distinction is a favourite trap.
Topic 12: Energy changes
Enthalpy changes, exothermic and endothermic reactions with their signs, entropy as order and disorder, and spontaneity through the relationship ΔG = ΔH − TΔS, with ΔG = 0 as the equilibrium criterion.
The calculations are formula-substitution once you keep your signs straight. Marks lost here are usually sign errors rather than understanding errors.
Topic 13: Rates of chemical reaction
The factors that change reaction rate (temperature, concentration or pressure, surface area, catalysts) each tied to a named experiment, such as HCl with sodium thiosulphate for temperature and marble chips versus powder for surface area. Also rate curves, activation energy, a qualitative treatment of collision theory and Arrhenius’ law, and light-driven reactions like the halogenation of alkanes.
Learn the experiments, not just the factors. JAMB describes the experiment and asks which factor it demonstrates.
Topic 14: Chemical equilibria
Reversible reactions, dynamic equilibrium, Le Chatelier’s principle and the equilibrium constant, with examples like steam on iron and the N2O4/NO2 system. The syllabus states plainly that no calculations are required here, which is worth knowing before you spend a weekend on Kc arithmetic that cannot be examined.
Le Chatelier prediction questions, on the other hand, appear constantly. Given a change in pressure, temperature or concentration, know which way the position shifts and why.
Topic 15: Non-metals and their compounds
The big descriptive chemistry block: hydrogen, chlorine and the halogens, hydrogen chloride, oxygen and its oxide classes plus ozone, sulphur and its compounds through to the contact process for H2SO4, hydrogen sulphide, nitrogen and ammonia through the Haber process, trioxonitrate(V) acid, the oxides of nitrogen and the nitrogen cycle, then carbon: its allotropes, CO2, the effect of CO on blood, coal, coke and synthesis gas.
The ion tests hiding in this topic are exam gold: the tests for Cl-, SO42-, SO32-, S2-, NH4+, NO3-, CO32- and HCO3- all live here, and at least one appears on virtually every paper. Make a single flashcard per ion and drill them.
Topic 16: Metals and their compounds
General metallic properties, sodium and its major compounds (NaOH by electrolysis of brine, Na2CO3 by the Solvay process, NaCl from seawater), calcium and the chemistry of cement and mortar, aluminium from bauxite, tin, the first transition series and its five characteristic properties, iron extraction and the advantage of steel, copper and CuSO4 preparation, and the composition and uses of the named alloys: steel, stainless steel, brass, bronze, duralumin, soft solder and others.
Extraction methods map to reactivity, and JAMB tests that mapping directly: why sodium needs electrolysis while iron settles for reduction in a furnace. The tests for Ca2+, Al3+, Fe2+, Fe3+ and Cu2+ belong on the same flashcard stack as the anions from Topic 15.
Topic 17: Organic compounds
The largest single topic. Tetravalency of carbon, IUPAC naming and empirical formulae, then class by class: alkanes with petroleum, cracking, reforming and octane number; alkenes with both structural and geometric isomerism and polymerization; alkynes through ethyne; benzene as the aromatic representative; alkanols including fermentation, local gin production and the Lucas test; alkanals versus alkanones and the test that separates them; alkanoic acids; alkanoates covering fats, oils, saponification and the soap-versus-detergent distinction; alkanamines; carbohydrates with the tests for simple sugars; proteins with the Ninhydrin, Biuret, Millon’s and xanthoproteic tests; and polymers, natural and synthetic, addition and condensation, thermoplastic and thermosetting.
Isomerism stops at six carbons, which limits how nasty the structure questions can get. Prioritize naming, functional-group identification and the distinguishing chemical tests, because those three skills answer the majority of organic questions ever set.
Topic 18: Chemistry and industry
Types of chemical industries, their raw materials, fine versus heavy chemicals, and biotechnology. A short, list-like topic that most candidates skip and that still produces a question or two most years. An hour of reading buys those marks.
How to actually use this syllabus
Treat the 18 topics as a checklist, but weight them honestly. Topics 4, 15, 16 and 17 carry several times the content of Topics 5 or 18, and the question distribution reflects that. A revision plan that gives every topic equal time is quietly overpreparing for Air and underpreparing for organic chemistry.
Work in this order if you are starting from scratch: the mole concept first, because everything numerical depends on it, then atomic structure and bonding, then acids and redox, then the descriptive blocks, then organic last and longest. Past questions come after each topic, not at the end of everything, and every question you get wrong should send you back to the syllabus entry it came from to see what you missed around it.
Pair the syllabus with JAMB-recommended textbooks rather than with summary pamphlets. The syllabus tells you the boundary; a proper textbook fills the territory inside it. And sit at least a few full computer-based practice tests before the real thing, because pacing on a CBT is its own skill.

Frequently asked questions
How many topics are in the JAMB Chemistry syllabus?
Eighteen, running from separation of mixtures to chemistry and industry. Lists showing 20 or 22 topics are the same syllabus with entries split and duplicated.
Is the JAMB syllabus the same as the area of concentration?
Yes. “Area of concentration” is the informal name candidates use; the official document is the syllabus, and it is the only authoritative version of what the exam can contain.
Does JAMB set questions outside the syllabus?
No. The syllabus defines the boundary of the exam. Anything on it can be tested and nothing off it should be.
Which topics are most important in JAMB Chemistry?
By content volume and question frequency: organic compounds, atomic structure and bonding, non-metals, metals, and acids, bases and salts. The mole concept from chemical combination underpins the calculations across the whole paper.
Are there calculations in every topic?
No. Chemical equilibria explicitly requires no calculations. The heavy calculation topics are chemical combination, gas laws, acids and bases (pH and titration), electrolysis (Faraday’s laws), energy changes and half-life under atomic structure.
Where do I download the official PDF?
From jamb.gov.ng under the syllabus section, or from the download button on this page. It is free either way; nobody should charge you for it.
Is the syllabus the same for UTME and Direct Entry?
The Chemistry syllabus published by JAMB serves candidates for the UTME, and DE candidates preparing for screening cover the same ground.

I am Jude Chinecherem, a final-year MBBS student at the University of Nigeria, Nsukka. I know what it feels like to want an education your family cannot afford. When my parents could not pay for my schooling, I had to learn how to find scholarships and work the system out on my own, with nobody to guide me. I came out the other side, and now I share everything I learned so the next student does not have to figure it out alone. This is the advice I wish someone had given me back then.
