CBSE Chemistry Class 12 Syllabus 2025: The Central Board of Secondary Education (CBSE) has announced the Class 12 Chemistry Syllabus for the academic year 2024-2025. This syllabus outlines what students will learn to master the basic principles and concepts of chemistry. It's designed to help students get ready for the 2025 board exams.
Chemistry is important because it deals with the properties, structure, and interactions of matter. Understanding these principles is crucial for many careers and for further education. The CBSE Class 12 Chemistry Syllabus 2025 gives students a clear view of the chapters and units they will study throughout the year. This helps them plan their studies well and stay organized.
CBSE Chemistry Class 12 Syllabus 2025 Overview
The CBSE Class 12 Chemistry Syllabus for the academic year 2024-25 includes a wide range of topics to give students a thorough understanding of chemistry's basic principles and concepts. The syllabus is divided into units such as Solid State, Solutions, Electrochemistry, Chemical Kinetics, d- and f-Block Elements, Coordination Compounds, Haloalkanes and Haloarenes, Alcohols, Phenols and Ethers, Aldehydes, Ketones and Carboxylic Acids, Amines, and Biomolecules.
Each unit is further broken down into chapters that cover specific topics in detail. For example, the Solutions unit includes types of solutions, ways to express the concentration of solutions formed from solids in liquids, solubility of gases in liquids, solid solutions, and Raoult's law. The Electrochemistry unit covers redox reactions, EMF of a cell, standard electrode potential, the Nernst equation, conductance in electrolytic solutions, and electrolysis.
