JEE Main Preparation Tips for Chemistry: Important Topics and Strategies

Last updated on July 18th, 2020 at 06:44 pm

JEE Main Chemistry is often considered as the easiest section of JEE Main examination. It also happens to be the key scoring subject for JEE Main 2020. The JEE Main Chemistry section consists more of application-based questions. These questions require concrete theoretical knowledge. With the JEE Main Preparation Tips for Chemistry, students will get a grip over the basic and complex concepts to attempt such questions. So, let us try to figure out how to study chemistry for JEE Main.

Latest Update: NTA has launched a mock test application named ‘National Test Abhyas for practising daily mock tests for JEE Main 2020.

As per the experts, the level of difficulty of all the subjects is quite similar. However, last year, in JEE Main many of the candidates found Chemistry moderate. The questions in Organic Chemistry were very difficult.

JEE Main Chemistry section follows the syllabus similar to what is covered in Class XI and XII Chemistry. As the scope of the syllabus is huge, candidates need to learn and retain the knowledge of a lot of equations, reactions, and formulae. This kind of root learning makes preparation tricky but the subject can render high scores.. This is because stress is not on conceptual application but information retention and appropriate recalling of the same.

JEE Main Preparation Tips For Chemistry: Pointers

A few tried and tested JEE Main Preparation Tips for Chemistry are given below.  This is enlisted by the experts for the convenience of candidates:

Start with Basics

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 them. After this, they can move on to higher-level books for advanced studies.

Use Limited Sources

It is true that studying from too many reference books can lead to confusion and you can also miss out on the most important topics. Therefore, candidates should limit their reference studies to the minimum. They should instead stress on making their own notes after each lesson. This will make the concept get internalized. Hence, it will be easier to commit to memory. Many ask, is NCERT enough for JEE Main Chemistry? You can check the best books for chemistry below.

Solve Maximum Mocks

Students should solve as many JEE Main mock test 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. Attempting as many previous year’s JEE papers as possible would give candidates a real-time feel and experience of taking the test.

Double Revision

Continuous revision of concepts, equations, and formulae would ensure better retention. Revision in Chemistry is required at least twice a week for all the topics/chapters. You should also revise topics which have been learned in the past along with a short revision of this week’s work.

Focus of High Weightage Topics

Once the entire syllabus has been covered thoroughly, students should deploy smart prep strategy. They should focus mainly on topics with higher weightage. It’s not that the entire syllabus should not be revised or practised. The weighted topics should be focused a little more than the rest.

For Physical Chemistry

The Physical Chemistry section consists of a lot of numerical problems. It covers topics such as 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. It will help in gaining accuracy.

For Inorganic Chemistry

Inorganic Chemistry’s most scoring topic is ‘Chemical Bonding and Periodic Tables’. Maximum questions from this unit are in the context of bond formation, bond breaking, and periodicity, S-Block, F-Block, D and F-Block elements etc.

For Organic Chemistry

JEE Main Organic Chemistry is mostly concept based. Candidates would be able to score really good marks if they 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.

NTA Content-Based Lectures (by IIT-PAL)

JEE Main Preparation Tips for Chemistry includes – utilising free resources. NTA has provided video lectures recorded by some reputed IIT Professors under the name of IIT-PAL on Youtube. These lectures are divided into subtopics for each chapter. There are more than 100 videos. They are of approximately 50 to 60-minute runtime. To access these videos-

  • Firstly, head over to the official website of NTA – www.nta.ac.in
  • Next, click on the ‘Students’ tab.
  • Then, under the ‘Test Practice’ section, select ‘Content Based Lectures’.

IIT-PAL Video Lectures

If students are not able to access the website above, they can also open Youtube and search for IIT-PAL. They will be able to watch the lecture they wish for.

Free Mock Tests by NTA

NTA has also provided free mock tests for JEE Main aspirants on their official website. These mock tests are an exact simulation of the actual examination. Also, this will help students understand how to attempt the examination in a computer-based environment. The only disadvantage here is that these are full mock tests and not subject-wise mock tests. Although, students can utilise this portal and if they wish, they can attempt mock tests of NEET as well for Physics and Chemistry to polish their basics. To access the mock tests head over to this website – https://nta.ac.in/quiz. After this, just select the examination and paper from 2020, 2019, 2018 and 2017 sessions. Once selected, start your mock test.
