Chemistry 2nd Year (Class 12) is published by the Punjab Education, Curriculum, Training and Assessment Authority (PECTAA), Lahore. The latest 2025–26 edition is based on the Updated/Revised National Curriculum of Pakistan 2023. It covers seventeen units from Group 2 Elements to Water, spanning inorganic chemistry, organic chemistry, biochemistry, and analytical techniques.
For FSC Part 2 students, Chemistry Class 12 is a key subject for both board exams and entry tests. Organic chemistry, biochemistry, and spectroscopy units are especially important for MDCAT and ECAT preparation. The PDF is available in three editions so students can use whichever version their college follows.

Chapter List
Unit 17 – Group 2 Elements
Covers the properties, reactions, and uses of alkaline earth metals (Group 2). Includes trends in physical and chemical properties down the group and important compounds.
Unit 18 – Transition Metals
Explains the general properties of transition metals including variable oxidation states, complex formation, catalytic behaviour, and the chemistry of important transition elements.
Unit 19 – Basics of Organic Chemistry
Introduces organic chemistry — carbon bonding, hybridisation, functional groups, homologous series, IUPAC nomenclature, isomerism, and types of organic reactions.
Unit 20 – Aromatic Hydrocarbons
Covers benzene and its derivatives, aromaticity, electrophilic aromatic substitution reactions, and the chemistry and uses of common aromatic compounds.
Unit 21 – Halogenoalkanes
Explains the nomenclature, preparation, properties, and reactions of halogenoalkanes including nucleophilic substitution and elimination reactions.
Unit 22 – Hydroxy Compounds
Covers alcohols and phenols — their nomenclature, preparation, physical and chemical properties, reactions, and industrial uses.
Unit 23 – Carbonyl Compounds and Carboxylic Acids
Deals with aldehydes, ketones, and carboxylic acids — their structure, nomenclature, preparation, reactions, and uses in industry and daily life.
Unit 24 – Organic Nitrogen Compounds
Covers amines, amides, and other nitrogen-containing organic compounds — their classification, preparation, properties, and reactions.
Unit 25 – Organic Synthesis
Introduces multi-step organic synthesis strategies, functional group interconversions, protecting groups, and planning synthesis routes for target molecules.
Unit 26 – Polymers
Covers addition and condensation polymers, natural and synthetic polymers, polymerisation mechanisms, and the uses and environmental impact of plastics and rubber.
Unit 27 – Biochemistry
Explains the chemistry of carbohydrates, proteins, lipids, nucleic acids, vitamins, and enzymes. Covers their structures, functions, and roles in living systems.
Unit 28 – Chromatography
Introduces chromatographic techniques including paper, thin-layer, column, and gas chromatography — their principles, procedures, and applications in chemical analysis.
Unit 29 – Spectroscopy-1
Covers electromagnetic spectrum, UV-Visible and infrared spectroscopy, and how these techniques are used to identify functional groups and structural features of organic molecules.
Unit 30 – Spectroscopy-2 NMR
Introduces Nuclear Magnetic Resonance (NMR) spectroscopy — the principles, chemical shift, splitting patterns, and use of NMR in determining the structure of organic compounds.
Unit 31 – Materials and Energy
Explores modern materials including ceramics, composites, semiconductors, and nanomaterials. Covers energy sources, fuel cells, solar energy, and nuclear energy.
Unit 32 – Medicine, Agriculture and Industry
Covers the role of chemistry in medicine (drugs, antibiotics), agriculture (fertilisers, pesticides), and industry (dyes, detergents, and industrial chemicals).
Unit 33 – Water
Explains the unique properties of water, water purification, hard and soft water, water pollution, sewage treatment, and the importance of clean water for health and industry.
