Generally, Chemistry is construed as the subject that demands rote learning. However, if it is pursued with the right strategy and technique, then it can be mastered easily. For instance, you can follow important chapters and topics of Chemistry for CBSE class 12th board exam. And it should be based on the lines of the data-driven strategy if you want to score more in the upcoming board exam of chemistry paper.
Additionally, you should take some time and reflect on what should be the Important Chapters and Topics of Chemistry for CBSE Class 12th Board Exam for you. Considering the fact that the chapters and its topics (with respect to any exam) are said to be important with reference to its marking weightage and other factors. These factors are “learning period”- the time needed to cover the chapter and master as well”, and the easiness or difficulty level of the chapter.
And to support you in this endeavour, the eminent faculty members of Career Point have prepared a detailed analysis of Important Chapters and Topics of Chemistry for CBSE Class 12th Board Exam as mentioned below.
Important Chapters and Topics of Chemistry: to pass the CBSE Class 12th Board Exam in less effort and less time
- The chapters like Biomolecules, Polymers, and Chemistry in everyday life are considered as easy for even below average studentsa. Moreover, it carries a weightage of 10 marks therefore it must not be missed.
- In physical chemistry, you must not miss the solution and Chemical Kinetics as its important and carries 5 marks.
- In inorganic chemistry, Coordination Chemistry (Naming) and Surface Chemistry (D/B) are important chapters and caries 10 marks each. P-block (Structure, Hybridization) and D-block (KMnO4, K2Cr2o7) are also important Chapters for CBSE Class 12th Board Exam as these two chapters carry 13 marks each.
- In Organic chemistry, Haloalkenes & Haloarenes are important chapter. Additionally, important topics are Name reactions are from:-
- Haloalkenes & Haloarenes
- Alcohol, Phenols & Ether
- Aldehyde, Ketones & Carbonylic
- Amines
Removed Chapters and Topics of CBSE Class 12th Chemistry
This time some chapters and topics are removed from the syllabus of CBSE class 12th chemistry, and the question paper of CBSE board exam will not carry questions from them. These removed chapters and topics are
- Solid State (Complete Chapter)
- P-Block (Group-15)
