Tips To Get 90+ Marks In CBSE Class 12 Chemistry

CBSE Class 12 Chemistry is an important subject for science stream students. Those who have good command over basics can easily score 90+ marks in this subject. But for these students need to really put an effort the whole year and practice a lot before the board exam. Merely studying at last moment for 1 or 2 months will not give any result. Students need to study Chemistry with full concentration and consistency from the start of the academic session. Here we have provided some tips which will help students to prepare for the CBSE Class 12 Chemistry Board Exams.

This subject also plays a crucial role in the competitive exam. So, preparing for the board exam will help students to perform well in the competitive exams as well. What they need is a regular practice and thorough understanding of the chapters. By going through this article students will get to know how to prepare for CBSE Class 12 Chemistry Exam and after that, they can plan their studies accordingly.

CBSE Class 12 Chemistry Preparation Tips

The CBSE Class 12 Chemistry subject is divided mainly into 3 parts:

  1. Physical Chemistry
  2. Organic Chemistry
  3. Inorganic Chemistry

Here are the ways to prepare for each section of chemistry in details. But before going into the depth, have a look at the CBSE Class 12 Chemistry Syllabus.

Physical Chemistry

If a student has a strong mathematical calculation capability and formula application skill then it’s will be a plus point for preparing the Physical Chemistry. The chapter like Electrochemistry, Chemical kinetics, Solutions, The solid state, Surface chemistry comes under this category. This basically consists of 23 marks and has 33% of weightage of the whole paper.

Unit No. Topic Name Marks
Unit I Solutions 23
Unit II Electrochemistry
Unit III Chemical Kinetics
Unit IV Surface Chemistry

Students should understand the topics from the NCERT textbooks and solve the exercise problems. As this portion mostly consists of numerical so students should practise different types of problems and concentrate on quick calculation using the log table. To remember all the formulas, students must note down all formulas at one place with examples. This will also help them in quick revision during exam timing.

Organic Chemistry

The organic chemistry deals with the vast majority of the compounds we see around us. If students have covered the basics of organic chemistry then they can ace this portion easily with full dedication and hard work. The organic chemistry is asked for 28 marks in the board exam. These topics mainly constitute the reactions, IUPAC naming of compounds, use of the different reagent to test the presence of the compounds.

Unit No. Topic Name Marks
Unit VIII Haloalkanes and Haloarenes 28
Unit IX Alcohols, Phenols and Ethers
Unit X Aldehydes, Ketones and Carboxylic Acids
Unit XI Organic Compounds containing Nitrogen
Unit XII Biomolecules
Unit XIII Polymers
Unit XIV Chemistry in Everyday Life

Some important reactions that students must make a separate note are:

(a) Phenols-Carboxylic Acid
(b) Aldehyde-Ketone
(c) 1,2,3 alcohols
(d) 1, 2, 3 amines

The important name reactions such as Williamson, Wolff-Kishner, Hell-Volhard-Zelinsky, Clemmensen Reduction are directly asked in the exam for 5 marks. So students must practice these reactions and it should be in their fingertips.

Inorganic Chemistry

This is considered to be a difficult part of class 12 chemistry. Students must memorize the periodic table and know about the properties of p-Block, d-Block and f-Block element. The questions asked in the exams are mostly from the NCERT Class 12 Chemistry textbook, thus students must practice the exercise problems of the chapters. The Inorganic chemistry is asked for 19 marks in the paper.

Unit No. Topic Name Marks
Unit V General Principles and Processes of Isolation of Elements 19
Unit VI p -Block Elements
Unit VI d -and f -Block Elements
Unit VII Coordination Compounds

With the help of the short notes and adequate revisions, students will be able to handle inorganic chemistry easily.

Practice Sample Papers and Previous Years Papers

To score above 90 marks in chemistry, practising CBSE Class 12 sample papers are essential. Through these students can analyse their exam preparation. Solving the previous year class 12 Chemistry question papers will provide students an idea of the exam pattern and type of questions asked in the exam. They will also get to know the difficulty level of the exam and questions that are repeated in the exam. Based on that they can figure out the important questions. Hence, it is advised to students to solve the question papers on daily basis once they are done with the syllabus. Analyse the weak points and work on them to improve the performance.

We hope students have found this information on “CBSE Class 12 Chemistry Preparation Tips” useful for their exam. Keep learning and stay tuned for further updates on CBSE and other competitive exams.
