Syllabus for Chemistry Class 11 CBSE

The Chemistry Class 11 CBSE is reduced by 30%. Students can download the compressed and updated syllabus from here. The CBSE Chemistry Exams may be held in March 2021. The practical exams will also be conducted by CBSE affiliated institution for conceptual assessment. The result of CBSE class 11th chemistry exams will depend on student’s analytical, judgment, and evaluation skills. 

Updated Chemistry Subject for Class XIth :

If you are interested in finding the core construction of any element or something around you then you should opt for the chemistry subject in class XI. This is one of the required subjects of the Science stream. The new modernized  syllabus of CBSE class XI the Chemistry provides students to

  1. Get acquainted with the newly developed areas like industrial chemistry, biomolecules, natural resources, synthetic materials.
  2. Students also get familiar with units of physical measures floated by scientific bodies like IUPAC and CGPM and New formulations and classification of elements and compounds, symbols.
  3. Due to the Covid-19 crisis, many new updated topics have been removed for the 2021 examinations. Students should get the reduced syllabus is only for the 2021 march exams. 

Chemistry Syllabus Scope:

The refined and regular  Chemistry syllabus will be covered in NCERT Books. Students can download NCERT books in PDF format for the Class 11th Chemistry Syllabus from hither. Students who opted for Chemistry in class 11th will stay with the same subject in class XII also. Students who have an investment in chemistry subject can explore professional events after 12th exams in some of the following general areas:

  1. Bioscientist
  2. Scientists, 
  3. Space scientists,
  4. Chemical engineers
  5. Medical researcher
  6. Atomic Researchers
  7. Engineers
  8. Adulteration Inspector

CBSE Class XIth Chemistry Reduced Syllabus 2021 

As we know Class XIth and XII syllabus for 2021 exams is decreased to 30%. Students can download the new updated and organized syllabus from Here. 

VSI  provides CBSE class XIth syllabus of  Accounts, Economics, Maths, Physics, Chemistry, English, and all the topics of arts, commerce, and science students.
