CBSE Class 11 Chemistry Syllabus 2022-2023 (New): Download in PDF



CBSE Class 11th Chemistry Syllabus 2022-2023 is available here for downloaded in PDF. This is the revised syllabus that has been released by the Central Board of Secondary Education (CBSE) for the current academic session. With the help of this syllabus, students will get to know the prescribed units along with their weightage for the CBSE Class 11 Chemistry Annual Exam 2022-2023. The board has continued with the curtailed syllabus therefore students must refer to the syllabus while studying a chapter to avoid reading the deleted portion. Also, check the CBSE practical evaluation scheme and experiments to be performed in CBSE Class 11 Chemistry.
