CBSE Class 12 Chemistry Latest Syllabus 2024-25

The Chemistry curriculum prepared by CBSE for Senior Secondary students for the academic session 2024-25 is all about making learning fun and exciting while laying a strong foundation for future studies and careers. It covers everything from basic concepts to recent developments in chemistry, showing students how it applies to real-world challenges like health, the environment, and industry. 

In the Class 12 CBSE chemistry syllabus 2024-25 the CBSE has added practicals of 30 marks along with a theory paper of 70 marks. The objective is to develop scientific temper and practical skills and help them discover how chemistry is related to other fields like physics and biology. Plus, the Class 12 chem syllabus also explores how chemistry impacts everyday life, sparking their curiosity and encouraging them to delve deeper into the subject. And all along the way, the syllabus is not just teaching about chemistry—but also gaining important life skills and values.
