CBSE Class 12 Chemistry Deleted Syllabus 2026-27
The CBSE Class 12 Chemistry Deleted Syllabus 2026–27 includes the removal of several chapters and topics from both Organic and Physical Chemistry to reduce the academic load on students. As per the latest CBSE curriculum, complete chapters like Surface Chemistry, Polymers, p-Block Elements, Chemistry in Everyday Life, and General Principles and Processes of Isolation of Elements have been deleted.
Additionally, Organic Compounds Containing Nitrogen has been renamed as Amines (Unit 9), and topics such as Cyanides and Isocyanides have been removed from the syllabus. With these changes, CBSE has shifted focus towards high-scoring and conceptually important units like Electrochemistry, Chemical Kinetics, Coordination Compounds, Haloalkanes and Haloarenes, Alcohols Phenols and Ethers, helping students prepare more effectively for CBSE Class 12 Board Exams 2026.

Here are a few last-minute tips to score well on your Class 12 Chemistry paper:
1. Skim through the NCERT books from cover to cover
As per the trends of the last few years, the Class 12 Boards question paper has questions all from the NCERT. So, you will need to remember every example of reactions, both organic and inorganic.
When practicing numericals, make sure you cover all the examples in between chapters and the exercise questions at the end of each chapter.
2. Concentrate on the units with the highest weightage
The following units hold the highest weightage for Class 12 Chemistry Board exams in decreasing order:
- p-Block Elements
- Aldehydes, Ketones and Carboxylic acids
- d-and f-Block Elements
- Solutions
- Electrochemistry
- Chemical Kinetics
3. Go through previous years’ question papers
Questions are often repeated in Chemistry and solving previous years’ question papers goes a long way to helping you ace in your Chemistry exams as it helps you with time management long with an understanding of the question pattern.
If you haven’t been solving these papers, don’t waste your time at this last minute. Instead, sit with a solved question paper book of previous years and go through each and every question.
Solve the trickier numericals in your notebook and mark the kind of Reaction questions asked often.
4. Memorise the formulae for Physical Chemistry
If you are good at Maths, you might find Physical Chemistry right up your alley. Physical Chemistry constitutes of Units 1 to 5 and constitutes a total of 23 marks. Write down and memorise all the formulae and make sure you solve at least one or two questions of the style you find most difficult.
Take the help of reference books to find several problems of similar styles to practice.
5. Practice Reasoning type Organic and Inorganic questions
In such questions, make sure you provide the correct reasons. The previous years’ questions will help you understand what kinds of questions are likely to be asked. In Organic questions of this type, provide the suitable diagram as well.
6. Concentrate on p-Block elements and Coordination Compounds chapters for Inorganic Chemistry
Inorganic Chemistry is a good target area for those who are good at theory. Units 6-9 which constitute Inorganic Chemistry carry a total of 19 marks. Memorising the reactions are very important here. You can expect around 8 marks or more to be asked from p-Block.
Noble gases and Halogens are important topics and often have questions asked from them. Practice these areas well.
From p-Block chapter, also practice drawing the structures of the different elements.
p-Block and d-Block elements cannot be learned quickly but if you have notes, it will be quick to revise.
7. Named reactions and conversions are very important
Units 10 to 16 constitute Organic Chemistry and this 29-mark portion is the heaviest bulk of the Class 12 Chemistry Board exam. True Chemistry lovers probably enjoy this section and don’t even consider it too difficult.
Named reactions are very important, as are questions such as Nucleophilic substitution/addition, Electrophilic substitution/addition.
Also revise and practice a couple of step-by-step conversion questions from one compound to another.
8. Practice IUPAC naming and the identification of compounds through different agents
IUPAC naming of compounds is important for 1-mark questions. You should go through the rules and practice a couple to make sure you understand this.
Vert short answer type questions can be asked on the identification of compounds though different agents and you should practice the same.
9. The last three chapters can fetch you 10 solid marks
The last three chapters of the book need to be read and learned mostly and you can score a solid 10 marks from the chapters Biomolecules, Polymers, and Chemistry in Everyday life.ADVERTISEMENT
So, take a breather and get on with your revision. Sleep for at least 6 hours and don’t freeze during the exam. All the best!
