Based on the updated CBSE curriculum for 2025-26, here is a short, chapter-wise overview of Class 12 Chemistry, including the marks distribution. The total theory paper is worth 70 marks.
Physical Chemistry (23 Marks)
- 1.Solutions (7 marks): This unit covers the properties of different types of solutions, focusing on concepts like concentration (molarity, molality), Raoult’s Law, and colligative properties (relative lowering of vapor pressure, elevation of boiling point, depression of freezing point, and osmotic pressure). It also includes the Van’t Hoff factor.
- 2.Electrochemistry (9 marks): The chapter explores redox reactions, electrochemical and galvanic cells, and the Nernst equation. You’ll study topics like specific and molar conductivity, Kohlrausch’s Law, and the working of different types of cells, including dry cells and fuel cells.
- 3.Chemical Kinetics (7 marks): This chapter deals with the rate of chemical reactions and the factors that influence them. Key concepts include rate law, order and molecularity of reactions, integrated rate equations for zero and first-order reactions, and the half-life of a reaction.
Inorganic Chemistry (14 Marks)
- 4.d- and f-Block Elements (7 marks): This unit provides an introduction to transition and inner-transition elements. Topics include their electronic configurations, general properties, and trends. You’ll also learn about the preparation and properties of important compounds like potassium dichromate and potassium permanganate.
- 5.Coordination Compounds (7 marks): This chapter focuses on the nomenclature, isomerism, and theories of bonding in coordination compounds, such as Valence Bond Theory (VBT) and Crystal Field Theory (CFT). It also highlights the significance of these compounds in qualitative analysis and biological systems.
Organic Chemistry (33 Marks)
- 6.Haloalkanes and Haloarenes (6 marks): You’ll learn about the nomenclature, preparation, and properties of organic compounds containing halogen atoms. The chapter focuses on substitution reactions and also discusses the environmental effects of some polyhalogen compounds.
- 7.Alcohols, Phenols and Ethers (6 marks): This unit covers the methods of preparation, physical properties, and chemical reactions of these functional groups. It also includes the acidic nature of phenols and the mechanism of dehydration of alcohols.
- 8.Aldehydes, Ketones and Carboxylic Acids (8 marks): This is a crucial and high-weightage chapter. It covers the nomenclature, preparation, and chemical properties of these carbonyl compounds. Important topics include nucleophilic addition reactions and the reactivity of alpha-hydrogens.
- 9.Amines (6 marks): The chapter deals with the classification, structure, nomenclature, and methods of preparation of amines. You’ll also study their basic character and the preparation and reactions of diazonium salts.
- 10.Biomolecules (7 marks): This unit provides an introductory overview of the chemistry of life. It covers the classification and structure of carbohydrates, proteins (including amino acids and denaturation), and nucleic acids (DNA and RNA). It also briefly touches upon vitamins.
Why You Need Class 12 Chemistry Chapter-Wise Notes 📝
Creating or using reliable chapter-wise notes offers several advantages that streamline your study process.
- Quick Revision: Instead of going through the entire textbook before an exam, you can quickly scan your notes to refresh your memory on crucial topics. This is particularly helpful for last-minute review.
- Conceptual Clarity: Notes condense complex information into digestible points. For challenging topics like organic reaction mechanisms or colligative properties, simplified notes with flowcharts and diagrams can make all the difference.
- Organized Learning: Breaking down the syllabus into individual chapters allows you to focus on one topic at a time. This prevents you from feeling overwhelmed and helps build a strong foundation.
- Memory Retention: The process of creating your own notes from the textbook helps you actively engage with the material, leading to better long-term memory.
How to Use These Notes Effectively: A 3-Step Strategy
- First Read (The Foundation): Read the NCERT chapter line-by-line. Don’t rush. Underline or highlight important text.
- Note-Making (The Active Step): Now, create your own notes or supplement pre-made notes with the pointers from your NCERT reading. Use your own words. Draw the diagrams yourself.
- Practice (The Key to Success): After each topic, solve the in-text questions and exercises from NCERT. Then, move to previous years’ question papers and sample papers. This is non-negotiable.
Pro-Tips for Scoring 95+ in Chemistry
- NCERT is Your Bible: 90% of the board paper is directly or indirectly from NCERT. Master it.
- Reaction Sheets are Gold: Maintain a separate notebook for all named reactions and mechanisms. Revise it daily.
- Numericals Need Practice: You cannot cram numerical problems. Solve at least 10 problems from each numerical topic weekly.
- Previous Year Papers are a Secret Weapon: They help you understand the paper pattern, marking scheme, and important questions.
