Tips for JEE Main chemistry 2021:

JEE Main chemistry section is considered the most fruitful section in obtaining good marks in comparison to physics and mathematics. It requires a lot of practice of chemical equations, bonds and numerical. One should make a habit of learning by writing the equations as frequently as possible because they cannot be remembered orally.

It is considered as the rank deciding subject in most competitive exams because it comprises mostly theoretical based questions in comparison to physics and mathematics and so it is also the most scoring subject. The main strategy to score well is to analyse previous year JEE Main question papers and strengthen the topics which have mostly occurred. To make the study process more efficient you can check your performance through online test series which are based on the exam pattern. There are 15-18 tests papers for JEE Mains and 9-10 tests papers of JEE Advance, after giving tests you will get your performance report which will help you find your area of improvements and your speed.

This section deals with the understanding and observing of the physical and chemical properties of different matter around us. It covers 40% of the JEE Main Chemistry paper and includes the basic concepts and formulae. A good tip is to make detailed notes on each topic and avoid skipping regular practice to crack these numerical questions.

Some important concepts in physical chemistry are:

  1. Mole concept

  2. Equilibrium

  3. Atomic structure

  4. Chemical Bonding

  1. Organic Chemistry:

It might seem difficult at first, but you can master this part with regular studying. The more you remember the reactions, structures and compounds thoroughly, the better. Do you know you can actually attempt this section in just 20 minutes if studied well? The trick would be to understand the fundamentals and mechanisms rather than learning by heart. Don't forget to make notes on the important topics and keep revising them every week.

Some important sub-topics for chemistry are:

  1. Hydrocarbons

  2. Organic compounds containing Halogens, Oxygens, Nitrogen

  3. Purification and Characterization of Organic Compounds.

  4. Nomenclature

  5. Polymers

  6. Chemistry in Everyday Life

  1. Inorganic Chemistry:

This is relatively much easier than any other section and doesn’t include any problem-solving questions. Therefore, this is a very time-saving section. Moreover, it contains very simple and straightforward questions that you can easily cover from NCERT XI and XII books.

Study the methods of preparation, uses, chemical reactions of compounds thoroughly as they are the important topics and cannot be missed.

Some important sun-topics in inorganic chemistry are:

  1. Coordination Compounds

  2. Classification of Elements and Periodicity in Properties

  3. s-block elements (Alkali and Alkaline earth)

  4. p-block elements

  5. d and f block elements

  6. Hydrogen

Practise conversions and reagents daily along with chemical reactions and their mechanisms. Daily practise and revision will help you make your mind stronger until JEE Main Exam.

With the right procedures, you can crack this hard nut without fail. You simply need to have self-confidence and keep practising via mock exams, which are extremely helpful. Remember, that this is the paper that can bring you the maximum scores, so do it well.

Have a question related to JEE Main ?

Hello,

Since the correction window is closed, you can't change the enrollment number online. You should immediately contact the JEE Main authority and email them with proof to see if they can help, as this is the only remaining option. Previous applicants' experience suggests it may be possible to resolve this issue by contacting the NTA directly.

I hope it will clear your query!!

Hello,
Yes, you can clear the exam in one and a half month if you study with the right strategy. Many students have prepared in a short time and still scored well by focusing only on the most important chapters and practicing questions daily. You need to revise high weightage topics from all three subjects and solve previous year papers regularly. Give mock tests every two or three days to understand your weak areas. Keep your schedule simple and consistent. If you avoid distractions and focus only on scoring chapters, it is possible to clear the exam in this time.
Hope this helps you.

Hello

If you have only December to complete the JEE Mains syllabus, the best strategy is to focus on high-weightage chapters in each subject to maximize your score in a short time. According to Careers360 analysis and past years’ trends.
