Chemistry carries a reputation for being difficult in JAMB, but the truth is that most candidates struggle because they study without direction. They flip through entire textbooks hoping to cover everything, and on exam day, they cannot recall the specific details JAMB actually tests. The solution is straightforward — master the area of concentration for JAMB Chemistry before you open any textbook, and your preparation becomes focused, efficient, and far more productive.
This guide delivers the complete area of concentration for JAMB Chemistry for the 2026/2027 UTME session. Every topic, subtopic, and question pattern is mapped out below, along with recommended textbooks and practical strategies to help you score 80 and above. All information is based on the official JAMB syllabus.
How the JAMB Chemistry Paper Is Structured
The JAMB UTME Chemistry paper contains 40 multiple-choice questions to be answered within the Computer-Based Test (CBT) format. These questions are drawn from three major branches of Chemistry — Physical Chemistry, Inorganic Chemistry, and Organic Chemistry — plus a small number of questions on Industrial Chemistry. Physical Chemistry consistently dominates the paper, accounting for over half the total questions.
The JAMB Chemistry syllabus is designed to test four core abilities: understanding basic chemical principles and concepts, interpreting scientific data, identifying the relationship between chemistry and other sciences, and applying chemical knowledge to industry and everyday life. Knowing these objectives is key to fully grasping the area of concentration for JAMB Chemistry because every question is built around one or more of these four goals.

Question Distribution by Section
Understanding how questions are spread across sections is just as important as knowing the area of concentration for JAMB Chemistry itself. The table below shows the typical distribution.
| Section | Estimated Questions | Approximate % of Paper |
| Physical Chemistry (Topics 1–10) | 24 – 30 questions | ~55–60% |
| Inorganic Chemistry (Topics 11–13) | 6 – 10 questions | ~15–20% |
| Organic Chemistry (Topics 14–15) | 6 – 10 questions | ~15–20% |
| Industrial Chemistry (Topic 16) | 1 – 3 questions | ~5% |
| Total | ~40 questions | 100% |
Physical Chemistry alone makes up roughly 55–60% of the paper. This is the single most important insight from the area of concentration for JAMB Chemistry. A candidate who thoroughly covers stoichiometry, atomic structure, gas laws, acids and bases, and electrolysis already has a strong foundation for answering the majority of questions.
Section-by-Section Study Guide
Physical Chemistry (~55–60% of Questions)
This is the largest and most important section. It spans Topics 1 through 10 in the table above and covers the fundamental principles that govern chemical behaviour. Here is what to focus on:
Separation Techniques: Know the principle behind each method — distillation separates liquids with different boiling points, chromatography separates components based on differential adsorption, filtration separates insoluble solids from liquids, and so on. JAMB tests both the method and the principle, so do not just memorise names.
Gas Laws and Kinetic Theory: Boyle’s law (P₁V₁ = P₂V₂), Charles’ law (V₁/T₁ = V₂/T₂), the combined gas law, and the ideal gas equation (PV = nRT) appear almost every year. Practise calculations involving temperature conversions to Kelvin and volume/pressure changes.
Atomic Structure and Bonding: Electron configuration (spdf notation), ionic and covalent bond formation, shapes of molecules (linear, tetrahedral, trigonal planar), electronegativity differences, and the properties of metallic bonds. This topic carries 4–5 questions on average.
Stoichiometry and Mole Concept: This is the calculation-heavy core of the area of concentration for JAMB Chemistry. Master mole-to-mass conversions, empirical and molecular formula derivations, reacting masses from balanced equations, and limiting reagent problems. JAMB always includes at least 3–4 calculation questions from this area.
Acids, Bases and Salts: pH calculations, strong versus weak acids/bases, indicators (methyl orange, phenolphthalein, litmus), neutralisation reactions, salt preparation methods, and buffer solutions. This is one of the most frequently tested topics in JAMB Chemistry.
Electrolysis and Redox: Faraday’s first and second laws, electrolysis of specific solutions (brine, dilute H₂SO₄, CuSO₄), factors affecting ion discharge, the electrochemical series, and corrosion prevention. Expect 4–6 combined questions from these two topics.
Inorganic Chemistry (~15–20% of Questions)
This section tests your knowledge of the periodic table, specific metals (sodium, calcium, aluminium, iron), non-metals (hydrogen, oxygen, nitrogen, chlorine, sulphur, carbon), and their compounds. Key areas include periodic trends (atomic radius, ionisation energy, electronegativity across periods and down groups), extraction of metals (especially aluminium from bauxite and iron from haematite in the blast furnace), properties and reactions of Group I, II, and VII elements, and the chemistry of common compounds like NaOH, CaCO₃, Al₂O₃, and FeSO₄. JAMB also tests identification reactions — colour changes, precipitate formation, and gas tests — so study qualitative analysis.
Organic Chemistry (~15–20% of Questions)
Organic Chemistry is the section where many candidates lose marks unnecessarily, yet it is one of the most predictable areas in the area of concentration for JAMB Chemistry. Focus on IUPAC nomenclature (naming alkanes, alkenes, alkynes, alkanols, alkanoic acids), isomerism (structural and geometric), types of organic reactions (addition, substitution, elimination, condensation, polymerisation), functional group chemistry (alkanols, alkanals, alkanones, alkanoic acids, esters), and practical applications like saponification (soap making), fermentation, and the chemistry of fats, oils, carbohydrates, and proteins. Questions on petroleum fractionation and cracking also appear regularly.
Industrial Chemistry (~5% of Questions)
Although this section contributes only 1–3 questions, those questions are usually straightforward. Study the Contact process (manufacture of H₂SO₄), the Haber process (manufacture of NH₃), the Solvay process (manufacture of Na₂CO₃), electrolytic production of NaOH from brine, and the environmental effects of industrial pollution (acid rain, greenhouse effect, ozone depletion). These are easy marks for any prepared candidate.

7 Strategies to Score 80+ in JAMB Chemistry
Knowing the area of concentration for JAMB Chemistry is only effective if you combine it with smart study habits. Here are seven strategies that work:
- Study Physical Chemistry first. It carries over half the paper. If you cover gas laws, atomic structure, stoichiometry, acids and bases, and electrolysis thoroughly, you already have a strong base score.
- Practise calculations daily. JAMB Chemistry includes 8–12 calculation questions. Practise mole concept, gas law, Faraday’s law, and enthalpy calculations until you can solve them quickly and accurately.
- Use past questions as a study tool. Solve at least 10 years of JAMB Chemistry past questions. You will notice recurring question types, especially in stoichiometry, periodicity, and organic naming.
- Learn equations, not just concepts. JAMB tests your ability to write and balance chemical equations. Practise writing equations for neutralisation, combustion, electrolysis, and organic reactions.
- Memorise the electrochemical series. K, Ca, Na, Mg, Al, Zn, Fe, Sn, Pb, H, Cu, Hg, Ag, Au — this series appears in electrolysis, corrosion, and redox questions. It is non-negotiable.
- Master IUPAC naming rules. Organic Chemistry naming questions are free marks if you know the rules. Practise naming compounds with up to 8 carbon atoms and identifying functional groups.
- Time your practice sessions. In the CBT, speed matters. Practise answering 40 Chemistry questions within the allotted time to build confidence and reduce exam-day panic.
