CBSE Class 12 Chemistry Syllabus 2025-26: CBSE (Central Board of Secondary Education) has released the new and updated Class 12 Chemistry syllabus for the academic year 2025-26. To be honest, it's not very different from the last year's syllabus, but there are few small updates you should know about.
CBSE Board Class 12 syllabus for Chemistry includes both theory and practicals. The theory part will be of 70 marks, and 30 marks are for practicals and internal assessment. That means you gotta focus on both – reading your books and also doing well in lab work.
Students can download the CBSE Class 12 Chemistry Syllabus PDF to see all the topics, chapter-wise weightage, exam pattern, and marking scheme. The cbse class 12 chemistry syllabus pdf also gives you details about the practical experiments and how your marks will be given.

If you're in Class 12 and studying Chemistry, downloading the Class 12 Chemistry Syllabus 2025-26 PDF can really help you in many ways. Let’s talk about some of the simple benefits:
The CBSE Class 12 Chemistry Syllabus 2025-26 is made to match with NCERT guidelines. It's very well-organised and helpful for exam preparation. It focuses on both understanding concepts and learning practical skills. So, students should really try to follow the Chemistry Class 12 syllabus and practice according to it. This will make your preparation stronger and more focused.
The CBSE Class 12 Chemistry syllabus for 2025-2026 encompasses various units, including: 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.
For the academic session 2025-2026, CBSE has streamlined the Class 12 Chemistry syllabus by omitting certain chapters to focus on core concepts. The deleted chapters include: Surface Chemistry, General Principles and Processes of Isolation of Elements, p-Block Elements, Polymers and Chemistry in Everyday Life
After the recent syllabus rationalization, the CBSE Class 12 Chemistry curriculum comprises 10 chapters, focusing on essential areas of physical, inorganic, and organic chemistry.
Students often find the chapter on Electrochemistry particularly challenging due to its complex concepts and mathematical formulations. However, perceptions of difficulty can vary among individuals, with some students finding topics like Chemical Kinetics or Coordination Compounds more demanding. Consistent study and thorough understanding can help in mastering these chapters.
