Chemistry 1st Year book (Class 11) is published by the Punjab Education, Curriculum, Training and Assessment Authority (PECTAA). The latest 2025–26 edition is based on the Updated/Revised National Curriculum of Pakistan 2023. It covers sixteen chapters from Periodic Table and Atomic Structure to Lab Safety and Practical Skills.
For FSC Part 1 students, Chemistry is one of the most important subjects for both board exams and entry tests. Each chapter in this book builds concepts step by step with clear theory, worked examples, and exercises. The PDF makes it easy to revise reactions, equations, and numerical problems anytime before the exam.

Chapter List
Chapter 1 – Periodic Table and Periodic Properties
Covers the modern periodic table, trends in periodic properties such as atomic radius, ionization energy, electron affinity, and electronegativity across periods and groups.
Chapter 2 – Atomic Structure
Explains the structure of the atom, subatomic particles, quantum numbers, electron configurations, and atomic models from Bohr to the quantum mechanical model.
Chapter 3 – Chemical Bonding
Covers ionic, covalent, and metallic bonds. Includes VSEPR theory, molecular geometry, polarity, intermolecular forces, and hydrogen bonding.
Chapter 4 – Stoichiometry
Deals with mole concept, molar mass, empirical and molecular formulas, balancing equations, limiting reagents, and percentage yield calculations.
Chapter 5 – States and Phases of Matter
Explains properties of gases, liquids, and solids. Covers gas laws (Boyle’s, Charles’, Ideal Gas Law), kinetic molecular theory, and phase diagrams.
Chapter 6 – Chemical Energetics
Introduces thermochemistry, enthalpy, Hess’s Law, bond energies, and calorimetry. Covers exothermic and endothermic reactions with numerical problems.
Chapter 7 – Reaction Kinetics
Covers rate of reaction, factors affecting reaction rate, rate laws, activation energy, and the Arrhenius equation. Includes collision theory and catalysis.
Chapter 8 – Chemical Equilibrium
Explains dynamic equilibrium, equilibrium constants (Kc, Kp), Le Chatelier’s Principle, and its applications in industrial processes.
Chapter 9 – Acid-Base Chemistry
Covers Arrhenius, Bronsted-Lowry, and Lewis theories of acids and bases. Includes pH, buffer solutions, titrations, and indicators.
Chapter 10 – Electrochemistry
Explains oxidation-reduction reactions, electrochemical cells (galvanic and electrolytic), standard electrode potentials, and Faraday’s laws of electrolysis.
Chapter 11 – Hydrocarbons
Introduces organic chemistry with alkanes, alkenes, and alkynes. Covers nomenclature, isomerism, and key reactions of each hydrocarbon class.
Chapter 12 – Nitrogen and Sulfur
Covers the chemistry of nitrogen and sulfur compounds, including oxides, oxyacids, and their industrial applications such as the Haber and Contact processes.
Chapter 13 – Halogens
Explains properties, reactions, and uses of halogens. Covers halides, halogenation reactions, and trends in the halogen group.
Chapter 14 – Atmosphere
Deals with the composition and layers of the atmosphere, air pollution, ozone depletion, greenhouse effect, and environmental chemistry.
Chapter 15 – Basic Separation Techniques
Covers laboratory techniques for separating mixtures: filtration, distillation, crystallization, chromatography, and solvent extraction.
Chapter 16 – Lab Safety and Practical Skills
A practical chapter covering laboratory safety rules, handling chemicals and equipment, basic practical techniques, and writing lab reports.

⬇ Download PDF (E-Learn Punjab)Who Should Read This
This book is for FSC Part 1 (First Year) science students preparing for the Punjab Board annual exam. It is also essential for students planning for MDCAT and ECAT, as Chemistry from Class 11 is heavily tested in both entry tests. Topics like atomic structure, stoichiometry, equilibrium, acid-base chemistry, and hydrocarbons are directly part of the MDCAT and ECAT syllabus.
Applicable Boards
This textbook is published by PECTAA and is used in Punjab Board colleges. Students from the Federal Board (FBISE) and AJK Board can also use it for reference, as the FSC Chemistry syllabus is largely the same across these boards. Students from Sindh and KPK boards will also find most chapters relevant.
FAQs
Is this the latest Chemistry book for FSC Part 1 Punjab Board?
Yes. The 2025–26 edition is the latest, published by PECTAA and based on the Updated/Revised National Curriculum of Pakistan 2023.
How many chapters are in Chemistry Class 11?
There are 16 chapters, from Periodic Table and Periodic Properties to Lab Safety and Practical Skills.
Is this book helpful for MDCAT and ECAT preparation?
Yes. Chemistry from FSC Part 1 is a major part of both MDCAT and ECAT. Topics like atomic structure, stoichiometry, chemical bonding, equilibrium, and electrochemistry are directly tested.
What is the difference between the 2025-26 and E-Learn Punjab editions?
Both follow the same NCP 2023 curriculum. The E-Learn Punjab edition is the digital version from the Punjab government’s e-learning platform. The 2025–26 edition is the latest printed version approved by PECTAA.
Can Federal Board students use this book?
Yes. The FSC Chemistry syllabus is very similar for Punjab and Federal boards. Federal Board students can use this book for additional practice and reference.
Is the PDF free to download?
