Chemistry is a crucial topic that imparts practical knowledge. Chemistry study is a must for any technical or medical vocation. Therefore, more focus on Chemistry is required for a good future. For the academic year 2022–2023, the CBSE Board has issued the Class 12 Chemistry Syllabus under revision. The new curriculum will resemble the CBSE Class 12 Chemistry 2019-2020 Syllabus, according to the Central Board of Secondary Education. No chapters have been removed from the current curriculum or newly added. The theoretical portion of the Class 12 Chemistry Syllabus will be worth 70 points, and the assessment system will be worth 30 points. Solutions, Electrochemistry, Chemical Kinetics, d- and f-Block Elements, Coordination Compounds, Haloalkanes and Haloarenes, Alcohols, Phenols and Ethers, Aldehydes, Ketones and Carboxylic Acids, among other topics, are covered in the CBSE Class 12 Chemistry Syllabus 2022-23.
