CBSE Class 11 Chemistry Syllabus 2023-24: With the start of the new academic year 2023-24, the CBSE board has also released the new syllabi for all the subjects. Due to the recent pandemic, we all trying to get stability and so are the educational boards. After the pandemic, there were certain realisations happened in the academic field and changes were made around that. Now, education is more about conceptual learning rather than the traditional way of overburdening students’ bags. This same is mentioned in the 2020 NEP guidelines released during our struggle with COVID-19. One of the NEP guidelines supports the above-mentioned statement, the guideline is “emphasis on conceptual understanding rather than rote learning and learning-for-exams.” To have complete information on the new education policies read the NEP guidelines.
Before starting with the deleted topics it is important for the students and teachers to know the complete syllabus for 2023-24 Class 11 Chemistry so that they can see the changes. Read the CBSE Class 11 Chemistry syllabus 2023-24 here. Now we will be highlighting the changes made in the CBSE Class 11 Chemistry syllabus 2023-24. In the recent syllabus of Class 11 Chemistry, the CBSE board has introduced major changes. Some of the traditional units students were dealing with are now completely removed from the syllabus. Whereas, there are a few units that have a few additions. Read more to know the changes.

CBSE Class 11 Chemistry Updated Syllabus 2023-24
The below-mentioned units are final for the 2023-24 Class 11 Science batch for their Chemistry subject. Most of the units have the same content except two. Check below the list of topics added to the CBSE Class 11 Chemistry syllabus 2023-24.
| Unit Number | Chapter Name | Deleted Topics | Added Topics |
| I | Some Basic Concepts of Chemistry | - | - |
| II | Structure of Atom | - | Discovery of Electron, Proton, and Neutron, atomic number, isotopes, and isobars. Thomson's model and its limitations. Rutherford's model and its limitations. |
| III | Classification of Elements and Periodicity in Properties | - | Significance of classification, a brief history of the development of the periodic table |
| IV | Chemical Bonding and Molecular Structure | - | - |
| V | Chemical Thermodynamics | - | - |
| VI | Equilibrium | - | - |
| VII | Redox Reactions | - | - |
| VIII | Organic Chemistry: Some Basic Principles and Techniques | - | - |
| IX | Hydrocarbons | - | - |
These updates are for the academic year 2023–24, and the paper will be formed based on this. Thus, it was suggested to students that they note these down and not waste time preparing deleted units or chapters.
