| 2 | Chemistry in Everyday Life | 6–8 |
Volume 1 Summary
- Metallurgy: Concentration methods, extraction of Fe, Al, Cu, Zn, refining
- p-Block: Groups 13–18, anomalous behaviour, compounds (NH₃, HNO₃, H₂SO₄, SF₆, XeF₄)
- d and f Block: Transition metal properties, colour, magnetism, lanthanoid contraction
- Coordination: Werner's theory, IUPAC naming, isomerism, CFT, VBT
- Organic Nitrogen: Amines, diazonium salts, nitro compounds, Sandmeyer reactions
Volume 2 Summary
- Electrochemistry: Galvanic cells, Nernst equation, Faraday's laws, conductance, batteries
- Surface Chemistry: Adsorption, catalysis, colloids, Tyndall effect, coagulation
- Carbonyl Compounds: Aldehydes, ketones, carboxylic acids, reactions, distinguishing tests
- Bio-Molecules: Carbohydrates, proteins, nucleic acids, lipids
- Chemistry in Everyday Life: Drugs, food additives, soaps, polymers
Revision Strategy
Phase 1 — Concepts (Weeks 1–4)
Study each chapter with textbook. Highlight definitions, reactions, and named reactions.
Phase 2 — Notes and Practice (Weeks 5–7)
Make short reaction cards. Solve all textbook exercises and in-text questions.
Phase 3 — Previous Papers (Weeks 8–10)
Solve 5 years of TN HSE question papers. Identify repeated questions.
Phase 4 — Revision (Final week)
Revise formula sheets, reaction lists, and common one-mark facts.
Top Scoring Tips
1. Reactions: Write and re-write key reactions daily — organic reactions must be memorised 2. Diagrams: Blast furnace, Hall-Héroult cell, Daniel cell — draw with labels 3. One-mark questions: These are direct textbook facts — do not skip 4. Part IV (5-mark): Always write introduction, body, diagram, and conclusion 5. IUPAC nomenclature: Practice naming 10 coordination compounds
Board Exam Tips
- Never skip Bio-Molecules or Chemistry in Everyday Life — easiest chapters to score
- p-Block structures (XeF₄, PCl₅, SF₆) appear almost every year
- Electrochemistry numericals need formula cards — make them
