These Chemistry 1st Year notes cover the complete FSc Part-I (Intermediate, Class 11) Chemistry syllabus set by the Punjab Education, Curriculum, Training and Assessment Authority (PECTAA), following the 2025-26 edition of the PECTAA chemistry book, chapter by chapter, based on the Updated/Revised National Curriculum of Pakistan 2023.
The series includes all 16 chapters, from the periodic table and atomic structure through chemical bonding, stoichiometry, states of matter, energetics, kinetics, and equilibrium, into acid-base chemistry, electrochemistry, and organic and inorganic descriptive chemistry, ending with practical laboratory skills. Each chapter includes key concepts, definitions, formulas, diagrams, short and long questions, and MCQs.
What This Book Covers
The first nine chapters build the physical chemistry foundation: the periodic table and periodic properties, atomic structure, chemical bonding, stoichiometry, states and phases of matter, chemical energetics, reaction kinetics, chemical equilibrium, and acid-base chemistry.
The next four chapters move into electrochemistry and descriptive inorganic and organic chemistry: electrochemistry, hydrocarbons, the chemistry of nitrogen and sulfur, and the halogens.
The final three chapters apply chemistry to the atmosphere and the practical chemistry laboratory: atmospheric chemistry and air pollution, basic separation techniques, and lab safety and practical skills, including titration and qualitative salt analysis.
What’s Inside Every Chapter
- Clear explanation of every key concept
- Important definitions and key facts
- Labelled diagrams and illustrations
- Short and long questions with full answers

- Quick revision summary and exam tips at the end of each chapter
Who These Notes Are For
These notes are written for FSc Part-I (1st Year) students studying under the PECTAA Board (Punjab Education, Curriculum, Training and Assessment Authority) syllabus, and are equally useful for quick revision by students preparing for entry tests that include Chemistry.
How to Use These Notes
Read the key concepts of a chapter first, memorise its definitions and formulas, then attempt the short, long and objective questions to check your understanding. Revisit the revision summary and exam tips before your test or exam.
