Quick hacks to prepare Chemistry for JEE Main 2020

Chemistry is considered as a scoring part of the JEE Main exam. Chemistry Bench has listed quick preparation tips for JEE Main Chemistry, compiled by our experts for aspirants.


First, preparing JEE Main Chemistry needs tons of patience in practising conversions, numerical and revision of the theory. If you talk to candidates who have cracked the JEE (Mains) and Advanced, you will learn that consistent high scores in Chemistry subject will put you right in the driver’s seat.

Chemistry involves systematic study and learning. Don’t think “Ratta Marna” or ‘rote learning’ of formulae, equation and reactions can help you master Chemistry; you need to follow a systematic approach with a daily study plan involving preparation and revision of concepts.

JEE Chemistry can be divisible into three parts:
1. Physical & General Chemistry
2. Organic Chemistry
3. Inorganic Chemistry

Now, let’s dealt with these topic-wise in terms of preparation, study tips and avoiding common mistakes while preparing.

Preparation tips for JEE Main Physical & General Chemistry

Physical Chemistry deals with the study of physical and chemical properties of matter and physical things around us. It forms the main portion of JEE Chemistry, at least covering 30%-40% of the JEE examination paper. The best way to study Physical Chemistry is to develop detailed notes on every single topic in Physical chemistry. Topics such as Some Basic Concepts in Chemistry, States of Matter, Atomic Structure, Chemical Bonding and Molecular Structure, Chemical Thermodynamics, Solutions, Equilibrium, Redox Reactions and Electro-chemistry, Chemical Kinetics and Surface Chemistry are conceptually vital, and you need to thoroughly understand and learn related pertinent concepts and formulae. Furthermore keep practising questions. You can solve JEE Chemistry Numericals only through regular learning and practises.

How to prepare for JEE Main Organic Chemistry?

Organic chemistry can seem challenging to get the hang of to start with. This is because you need to remember compounds, reactions, structures and mechanisms during the exam. Nevertheless, it is important to learn the Organic part of Chemistry thoroughly to score well and avoid negative scores as the questions expected are fairly straightforward without confusing answers.

The best part is that unlike Physical chemistry there is no need for mathematical calculations or arithmetic. If you are crystal clear with the subject, the entire portion can be attempted easily in less than 20 minutes.

Here are the compete unit topics of Organic Chemistry: Purification and Characterization of Organic Compounds, Some Basic Principles of Organic Chemistry, Hydrocarbons, Organic Compounds Containing Halogens, Organic Compounds Containing Oxygen, Organic Compounds Containing Nitrogen, Polymers, Biomolecules, Chemistry In Everyday Life, and Principles Related to Practical Chemistry.

We recommend studying organic chemistry structures and reactions thoroughly. It is important to develop a routine mechanism than retorting to rote learning, and prepare notes of all the important topics scheduled for revision on a weekly basis.

How to prepare for JEE Main Inorganic Chemistry?

Considered by aspirants as the easiest part, JEE Inorganic Chemistry does not involve any problems or formulae or calculations to solve. It is either you provide an answer or not, and move on to the next question. The whole portion of Inorganic Chemistry can be attempted easily in less than 20 minutes. Inorganic Chemistry questions are generally conceptual.

Here are the complete unit topics of Inorganic Chemistry topics to focus: Classification of Elements and Periodicity in Properties, General Principles and Processes of Isolation of Metals, Hydrogen, S – Block Elements (Alkali and Alkaline Earth Metals), p- Block Elements, d – and f – Block Elements, Co-Ordination Compounds and Environmental Chemistry.

Final thoughts:

1. Develop a clear concept of any topic, application skills and focus on completing the syllabus before embarking upon anything new while preparing for JEE Chemistry.
2. Chemistry numerical are fairly simple when you practise and correct mistakes that you make all along. It is important that you pay attention to the details when you attempt to solve a question.
3. Once you are done with the organic part, give yourself sufficient time to solve numerical problems in general chemistry, and then move on to inorganic chemistry.
4. Make yourself strong in any two of the three sections in JEE Main Chemistry. For instance, if you fail to deliver big time in the organic part, you should be better off performing well in Physical and Inorganic sections.
5. Always attempt theoretical questions first before moving on to the numerical ones. Never spend the first 15 to 20 minutes attempting numerical questions.
6. Attempt a minimum of 10-15 previous year papers before appearing for the JEE exam. This exercise will shape your mental ability to counter tough questions in the test.
