JAMB Syllabus For Chemistry 2026 Released: Area of Concentration for Aspirants

Let’s be honest, preparing for JAMB can feel like a battlefield, and Chemistry is one of those subjects that can either boost your score very high or drag it down. Every year, many students panic because they don’t know what to expect, and many end up reading “everything” instead of focusing on the areas that are most important. That’s why the JAMB Syllabus for Chemistry 2026 is best for you. it doesn’t just tell you what to study, it tells you how to study smart.

Now, let’s break down how JAMB sets its Chemistry questions, the textbooks that can help you, and how best to prepare very well.

Full Breakdown of Areas of Concentration in JAMB Chemistry 2026

If you’re preparing for JAMB Chemistry in 2026, I’ve got some good news: you don’t need to study the entire Chemistry universe to score high. What you need is focus, yes, laser-sharp focus on the areas JAMB actually cares about. And the great thing? JAMB tells us those exact areas through the syllabus.

That’s what I’m going to break down here for you, clearly, simply, and in a way that you’ll remember long after you close this page.

Ready? Let’s dive right into it.

1. Structure of the Atom and Periodic Chemistry

This is JAMB’s favorite starting point. You’ll almost always see questions about:

Atomic structure (protons, neutrons, electrons)

Isotopes and their uses (like in medicine and agriculture)

Periodic table trends, ionization energy, electronegativity, atomic radius

Electron configurations and periodicity

2. Chemical Bonding

Bonding is like the “grammar” of Chemistry. Without it, nothing makes sense. Expect questions from:

Ionic, covalent, and metallic bonds

Hybridization and orbital theory (s, p, sp³ hybridization)

Hydrogen bonding and van der Waals forces

Bond polarity and electronegativity differences

3. Stoichiometry and Mole Concept

If Chemistry were a football match, this would be the midfield, it controls everything. Here’s what to master:

Mole concept and Avogadro’s number

Chemical equations and balancing reactions

Limiting reagents and percentage yield

Empirical and molecular formulas

Molar volume of gases at STP

4. States of Matter and Gas Laws

This is another hot spot for JAMB:

Boyle’s Law, Charles Law, and Gay-Lussacs Law

Ideal Gas Equation (PV = nRT)

Kinetic molecular theory of gases

Real gases vs ideal gases

Changes of state (melting, boiling, sublimation)

5. Energy and Thermodynamics

Yes, JAMB will test your understanding of how energy flows in chemical reactions:

Enthalpy changes (endothermic vs. exothermic reactions)

Heat capacity, calorimetry, and Hess’s Law

Bond energy calculations

Activation energy and energy profiles of reactions

6. Chemical Kinetics and Equilibria

This is where Chemistry becomes “alive” because it deals with how reactions actually happen. Expect:

Factors affecting rate of reaction (temperature, concentration, surface area, catalyst)

Collision theory

Equilibrium concepts (dynamic equilibrium, reversible reactions)

Le Chatelier’s Principle (predicting the effect of changes in conditions)

Equilibrium constants (Kc, Kp)

7. Acids, Bases, and Salts

This one is always loaded with questions. JAMB tests your knowledge of:

Definitions (Arrhenius, Bronsted-Lowry, Lewis)

pH calculations and indicators

Neutralization and titration

Hydrolysis of salts

Buffer solutions and their applications

8. Redox Reactions and Electrochemistry

This is where Chemistry meets electricity, and JAMB never misses it:

Oxidation numbers and balancing redox reactions

Electrolyte (NaCl, HSO₄, CuSO₄, etc.) electrolysis

The Laws of Electrolysis by Faraday Both galvanic and electrolytic electrochemical cells

Calculations of EMF and standard electrode potentials

9. Organic Chemistry 

JAMB has a knack for twisting this vast section. Expect:

Hydrocarbons are, alkanes, alkenes, alkynes, and aromatic hydrocarbons.

The amines, alcohols, ketones, carboxylic acid, and esters are functional groups.

As per IUPAC nomenclature, the correct compound names.

reactions of organic compounds (substitution, addition, and elimination)

Both artificial and natural polymers.

10. Inorganic Chemistry 

You will be tested on your understanding of elements and their compounds.

Chemistry of Alkali Metals (Group I) and Alkaline Earth Metals (Group II)

Colored compounds and transition metals

Characteristics of Group VII halogens

Sulfur, nitrogen, oxygen, and their compounds

Industrial procedures (Haber, Contact, and Solvay)

11. Environmental Chemistry and Practical Chemistry

JAMB is including more things about the real world in Chemistry, so expect:

Pollution of air and water (greenhouse gases, acid rains, ozone holes)

Water purification and sewage treatment.

Food Chemistry (carbohydrates, proteins, fats, oils)

Lab equipment, safety and standard experiments (titration, gas tests)

JAMB’s Pattern of Setting Chemistry Questions

Here’s a little secret: JAMB is not as unpredictable as most students think. In fact, Chemistry questions usually follow a certain pattern, and if you’ve taken time to analyze past questions, you’ll notice the trend.

Number of Questions: You’ll face 40 Chemistry questions in total, and they usually cut across Physical, Organic, and Inorganic Chemistry, plus a few from Environmental and Practical Chemistry.

Calculation-Heavy Sections: Be ready for questions on mole concepts, gas laws, titration, and thermodynamics. These are calculation-based, but the good news is JAMB often repeats the style of these questions, just with different numbers.

Theory & Conceptual Questions: Don’t underestimate theory-based questions. Things like atomic structure, periodic trends, organic reactions, and environmental chemistry usually appear in direct, multiple-choice form.

Repetition of Topics: JAMB is known for recycling questions and they do this alot of times. For example, a mole concept question from 2018 might appear again in 2023 with just a slight tweak. That’s why past questions are treasured very well.

Recommended Chemistry Textbooks for JAMB 2026

One of the biggest mistakes JAMB candidates make is relying on just one textbook. Chemistry is too broad for that. The right textbooks can simplify the syllabus and give you examples close to what JAMB actually sets.

Here are the top recommended ones:

1. New School Chemistry by Osei Yaw Ababio

This book is a classic. If you’re struggling with Organic or Inorganic Chemistry, this book breaks it down in a student-friendly way.

2. Essential Chemistry by I. L. O. Odesina & J. U. Okorie

Straight to the point, concise, and perfect for quick revision. Many students in Nigeria swear by this book.

3. Practical Chemistry for Schools and Colleges by Uche N. B.

Since JAMB loves practical-related questions (like titration, qualitative analysis, and lab techniques), this book is your go-to.

4. NERDC-Approved Chemistry Textbooks

These are designed in line with the Nigerian secondary school curriculum and align perfectly with JAMB’s style.

5. JAMB Chemistry Past Questions (Official Compilations)
