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.

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.
