Important of CBSE Class 12th Chemistry Syllabus 2023-24

Higher Secondary is the most important stage of schooling as special discipline-based, content-oriented courses are introduced at this time. Students reach this level after 10 years of general education and opt for chemistry to pursue their career in vocational courses like basic science or medicine, engineering, technology, and study courses in practical areas of science and technology at the tertiary level. Therefore, there is a need to provide the learners with adequate conceptual background in Chemistry, which will enable them to face the challenges of academic and vocational courses after the senior secondary level.

The new and updated curriculum is based on a disciplinary approach with rigor and depth taking care that the curriculum is not overwhelming and at the same time it is internationally comparable. There has been a tremendous change in the knowledge related to the subject of chemistry during the last decade. Many new fields like synthetic materials, biomolecules, natural resources, and industrial chemistry are coming up in a big way and deserve to be an integral part of the chemistry curriculum at the senior secondary level.

Internationally, new formulations and nomenclatures of elements and compounds, symbols, and units of physical quantities issued by scientific bodies such as IUPAC and CGPM are of utmost importance and need to be included in the updated curriculum. The revised syllabus takes care of all these aspects. There is more emphasis on new nomenclature, symbols, and formulations, the teaching of fundamental concepts, application of concepts in chemistry to industry/technology, logical sequencing of units, removal and repetition of obsolete material, etc.
