Updated and Reduced Syllabus for Chemistry Class 11 CBSE: 2021

The Chemistry Class 11 CBSE is reduced by 30% and Students can take the compressed and updated syllabus from here. The CBSE Chemistry Exams may be held in March 2020-21. The practical exams will also be conducted by CBSE affiliated organization for conceptual assessment. The result of CBSE class 11th chemistry exams will depend on student’s reasoning, judgment, and evaluation skills. 

Updated Chemistry Subject for Class XIth :

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

 

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