Karnataka Board 1st PUC Chemistry Syllabus 2020-21


For students, who want to know more about any of the basic concepts of Chemistry with clear cut details, as to its importance, study the laws of chemical combinations, atomic models or subatomic particles, properties of elements or even learn about the kinetic molecular theory of gases and get a general introduction to Organic Chemistry, they will find the Karnataka Board Class 11 Chemistry Syllabus to be very useful. From the units 1 to 14, the Chemistry book based on the 1st PUC Chemistry syllabus and curriculum will cover a wide variety of chapters on these topics and concepts.

With details and proper information about each topic covered under Chemistry, the Karnataka 1st puc syllabus for Chemistry will help students to know their weakness on any particular concept covered by 1st puc Chemistry. This will also help the students to bridge the gap at an early stage.

The 1st PUC Chemistry syllabus can also act as a basis for teachers to frame the Chemistry question papers, as they will have to try and include questions from all the units taught during the academic year. The concepts will include topics from Physical as well as Organic Chemistry. The 1ST PUC Chemistry syllabus was reduced for the academic year 2020-21. Please find it below:
