Chemistry subject is considered as easiest and it happens to be the key scoring subject for JEE Main. The Physics section comes with application based questions. Students need to have a grip over the basic concepts to attempt such questions.
As per the experts, the level of difficulty of all the subjects is quite similar. However, last year, JEE Main many of the applicants found Chemistry tough, questions on Organic Chemistry were tough.
JEE Main Chemistry follows the syllabus covered in Class XI and XII Chemistry paper. As the scope of the syllabus is, candidates need to learn and retain in mind a lot of equations, reactions, and formulae. This kind of rote learning makes preparation tricky but renders the subject a high-scoring one as stress is not on conceptual application but information retention and appropriate recall.
Each of the three sections in JEE Mains has an equal number of questions; as such, the Chemistry section consists of 25 compulsory questions bearing 4 marks each. The questions will cover Physical Chemistry, Organic Chemistry, and Inorganic Chemistry. The table below depicts unit-wise weightage for each of the sub-sections of Chemistry.
|Unit||Overall Weightage (in percentage)||Important Topics||Topic Weightage (in percentage)|
|Physical Chemistry||35.6||Basic Concepts||7.4|
|States of Matter and Solutions||23.2|
|Redox and Electrochemistry||8.4|
|Organic Chemistry||34.7%||Basic Principles||6.33|
|Hydrocarbons and its Substituents||6.33|
|O containing Compounds||8.33|
|N containing Compounds||3.00|
|Biomolecules & Polymers||5.67|
|Environmental & Everyday-life Chemistry||1.67|
|Inorganic Chemistry||29.7%||Coordination Compounds||14.9|
|Chemical Bonding and Molecular Structure||21.8|
|Classification of Elements and Periodicity||8.9|
|D & F Block Elements||24.7|
|Hydrogen and S-block Elements||12.9|
Pointers for Preparation
A few tried and tested preparation tips from subject experts are listed below for the convenience of candidates:
- In preparation for JEE Main Chemistry, the go-to textbook are the NCERT publications. NCERT books are the most reliable ones in terms of illustrations of concepts in a lucid language. Candidates can get their basics of the subject clear with the help of the NCERT books and move on to higher level books for advanced studies.
- However, it is advised that studying from too many reference books can lead to confusion and missing out on important topics. As such, candidates should limit their reference studies to the minimum and instead stress on making their own notes after each lesson so the concept gets internalized and thus easier to commit to memory.
- Students should also solve as many mock-papers as possible in order to score well in the exam. Consistent timed practice is the only way to ensure speed and accuracy in solving the questions in the JEE Mains exam. Attempting as many previous year’s JEE papers as possible would give candidates a real-time feel and experience of taking the test.
- Repeated revision of concepts, equations, and formulae would ensure better retention.
- Once the entire syllabus has been covered thoroughly, students should deploy smart prep strategy by focusing mainly on topics with higher weightage. It’s not that the entire syllabus should not be revised or practised, but the weighted topics should be focused a little more than the rest.
- Physical Chemistry section consists of a lot of numerical problems primarily from Redox Reaction, Mole Concept and their equivalences, Solid States, Gas Theory, Thermochemistry, and Thermodynamics. It is essential to have knowledge of proper formulae and/or logic to solve questions from these topics accurately and on time.
- Inorganic Chemistry’s most scoring topic is Chemical Bonding and Periodic Table and maximum questions from this unit are in the context of bond formation, bond breaking, and periodicity.
- Organic Chemistry is mostly concept based. Candidates would do well to focus on carbonyl groups reactions and their mechanism. Physical properties of organic groups, the polarization of carbonyl compounds, the hydrogen group, and carbon groups are the most frequently asked questions in the JEE Main Examination.
Suggested Readings for Chemistry
A few popular reference books apart from the must-read NCERT Chemistry Books (Class XI-XII) that are recommended in preparation of the JEE Main Chemistry section are:
|Name of Book||Author/Publisher|
|Concise Inorganic Chemistry for JEE||J D Lee|
|Inorganic Chemistry||O P Tandon|
|Textbook of Organic Chemistry||Arihant Publications|
|Organic Chemistry||P Tandon|
|Modern Approach to Chemical Calculations||R C Mukherjee|
|Physical Chemistry||O P Tandon|
|University Chemistry||Bruce M Mahan and Rollie J Meyers|
Chemistry is considered to be the most scoring section in the JEE Main Examination. Candidates will do well by following the prescribed syllabus while focusing on weighted topics, and consistent and rigorous practice of mock papers/previous year question papers in order to ensure high score is not only the Chemistry section but can also raise overall score and ranking in the test.
