CBSE Class 12 Chemistry preparation can be a lot tricky as it is divided into two books. Chemistry is the study of matter and its interaction with different matters. That makes it crucial for students who are aiming for a career in Analytical Chemist, Bio technologist, Chemical engineer etc to secure good marks in Chemistry. Namely, Organic Chemistry and Physical Chemistry. Both of them vary a lot in the amount of difficulty they pose to a Class 12 CBSE student. Most of the students find Organic Chemistry a lot more difficult than Physical Chemistry as it requires more understanding and there are a lot of formations and reactions. CBSE Class 12 students tend to find themselves lost in the seemingly over elaborate course and end up with bad marks in their board examinations. Chemistry, in general, is considered pretty difficult by CBSE Class 12 students. While Physical Chemistry is relatively easy as it is less elaborate than Organic Chemistry. Physical Chemistry requires an understanding of the concepts and the derivation of the formulas. There is not much to it due to which Class 12 CBSE students tend to undermine this part of Chemistry and end up neglecting it. Class 12th CBSE students generally fail to balance in both of the parts and time between the two subjects and end up with pretty bad marks in their board examinations. CBSE Class 12th students need to identify and prioritize between Organic and Physical Chemistry. The 2019-2020 Chemistry syllabus is divided into various units carrying a varying amount of marks. A breakdown and analysis of the same are given below:
| Unit | Title | Marks |
| I | Solid State | 23 |
| II | Solutions | |
| III | Electrochemistry | |
| IV | Chemical Kinetics | |
| V | Surface Chemistry | |
| VI | Isolation of Elements | 19 |
| VII | p-Block Elements | |
| VIII | d- and f-Block Elements | |
| IX | Coordination Compounds | |
| X | Haloalkanes and Haloarenes | 28 |
| XI | Alcohols, Phenols and Ethers | |
| XII | Aldehydes, Ketones and Carboxylic Acids | |
| XIII | Organic Compounds containing Nitrogen | |
| XIV | Biomolecules | |
| XV | Polymers | |
| XVI | Chemistry in Everyday Life | |
| Total | 70 |
As we can observe in the table above, Unit X to XVI carries most of the marks. These units are from the Organic Chemistry part of the curriculum. Unit I to V carry around 23 marks and are a part of Physical Chemistry. Students should make it a point to not to overlook such topics. Chemistry has 16 chapters which carry 70 marks and rest of the 30 marks are allotted for practical. Some of the most important parts of Chemistry are Electrochemistry, with D and F block elements, Haloalkanes and haloarenes, Alcohol, phenols and ethers, Aldehydes, ketones and carboxylic acid and polymers. All these chapters pose a considerable amount of difficulty for students and should be studied thoroughly by them. Students should also develop an understanding of the log table as it will help them in solving many problems in various chapters. The main thing that Chemistry requires is a deep understanding of different concepts. One just cannot mug up concepts as there is a vast number of concepts which is divided into two different books.
