JEE Main Chemistry Syllabus – Overview

Most students consider Chemistry as the most scoring subject In JEE Main examination. Chemistry questions are mostly moderate level or easy, primarily based on fundamental concepts. Hence, students who have mastery over the NCERT curriculum and have an excellent command of their basics do well in the Chemistry section. Questions in this subject are primarily theoretical and based on fundamentals. Also, there are fewer numericals, so it is quicker for students. 

Chemistry questions are not calculation-based but primarily depend on theory and sound fundamentals. Hence, students can answer these correctly and in much less time than the other two subjects. Chemistry questions are mainly asked from the NCERT 11th and 12th textbooks and the NCERT 11th and 12th exemplar books.

Students should thoroughly go through the JEE Main Chemistry syllabus and have a study plan covering all chapters and topics, including the revision time. They should know all the formulae, reactions, equations, and periodic tables as they are essential to answering the questions. 

Out of the three subjects for JEE Main, Chemistry is considered the most straightforward section in which students can score good marks. Experts recommend attempting Chemistry in the JEE Main exam, then either Mathematics or Physics.

• Atomic Structure – Important formulas and basic concepts. JEE Main often has many questions from this chapter. 

• Important topics – Wavelength of Electronic Transition, Quantum Numbers, and Ionisation Energy.

• States of matter, Solid-state 

• van der Waals equation, Kinetic Theory of Gases, Types of Molecular Velocity 

Why is it important for candidates to  attempt Chemistry first in JEE Main exam?

Academic experts have long advised students to start with Chemistry while attempting the JEE Main paper. Few reasons for the same are:

  • A significant portion of the JEE Main Chemistry syllabus is based on fact-based knowledge. Many questions are also based on factual knowledge, and therefore students can quickly solve these problems. The extra time left after Chemistry can be better utilised for the Mathematics and Physics section.
  • Most top students are able to complete the JEE Main Chemistry section in a maximum of 40-45 minutes, giving ample time for the other two sections.
  • This is the advisable order to solve questions during exams within the Chemistry section. Start with questions of Inorganic Chemistry (budget 6-8 mins), followed by Organic Chemistry (budget 12-15 mins), and finally attend the Physical Chemistry questions (budget 15-17 mins). The rest of the time, you will have to solve the 5 numerical problems.

JEE Main Chemistry Syllabus Preparation Tips:

JEE Main Chemistry Syllabus preparation tips for excelling in Physical Chemistry

For Physical Chemistry, thorough practice is most important. So you should keep a good set of books with lots of questions as part of your Chemistry study resources. You can safely rely on NCERT textbooks. Be careful when referring to other books, as they might contain additional topics that are not part of the official JEE Main Chemistry syllabus. You can refer to books from  RC Mukherjee, OP Tandon, N. Avasthi as they have a good set of problems. 

  • Students love Physical Chemistry because it does not require intense memorisation of chemical reactions and formulas. It involves various calculations, so experts advise students to keep practising to excel in Physical Chemistry. 
  • Chapters from NCERT Class 12 will have more weightage than Class 11. Two questions usually come from topics such as Solutions, Chemical Kinetics, Solid State, Atomic Structure in each JEE Main exam. Questions on Ionic Equilibrium, Thermodynamics, and Electrochemistry are found to be a bit tough. So practise these topics more.
  • Class 11 Physical Chemistry chapters are more challenging than class 12 chapters. Ionic Equilibrium, Thermodynamics, and Electrochemistry are the most difficult topics and require a clear understanding of theoretical concepts along with lots of question-solving practice. 
  • Class 12 chapters such as Solutions,  Solid State, Chemical Kinetics are easy, and students should master these topics to score fully in these questions. However, the chapter on Electrochemistry is tricky and requires theoretical and practical knowledge in the exam. Refer N. Avasthi for practising questions on this topic. 
  • Don’t miss out on Surface Chemistry. It’s a completely theory-oriented chapter, and you will surely get one question directly from the NCERT textbook in both JEE Main and JEE Advanced examinations.

JEE Main Chemistry preparation tips for excelling in Organic Chemistry

  • One-third of the JEE Main Chemistry questions come from Organic Chemistry chapters. Students should pay equal attention to both class 11 and 12 syllabus as the weightage is identical for both.
  • Students who have proper conceptual knowledge about these topics tend to solve the Organic Chemistry section faster, even if a few questions might appear a bit tricky. Many students face challenges in MCQs as they have a vague understanding of the topic and often get confused in multiple options. Experts advise students to fully understand JEE Main Chemistry syllabus from NCERT textbooks and solve complete exercises after each chapter. Many questions come directly from NCERT, and students can score quickly. 
  • Having a solid understanding of General Organic Chemistry at the start of the JEE Main Chemistry Syllabus is crucial. The conceptual understanding, including the mechanisms and exceptions covered in this topic, becomes the base in all the later Organic Chemistry chapters. 
  • Concepts from Acidity, Basicity, and Resonance are also required in many other JEE Main Chemistry syllabus chapters. So prepare these topics thoroughly and solve multiple question papers involving problems to determine the order of acids and bases.
  • Few topics are straightforward to understand and score good marks with less preparation time. These chapters are Chemistry in Everyday Life, Biomolecules and Polymers, and Classification of Elements in Organic Compounds.
  • Knowledge of topics and concepts around Mechanisms of Reactions and the reagents used in the reactions is important. Also, the topic of Aromatic Compounds and their reactions is important. It has been observed that these reaction-based questions come in both JEE Main and JEE Advanced question papers. So preparing well can help you score higher marks.
  • One important tip that has worked for many students is to prepare a list of exceptional behaviours of reactants, reagents and substrates after completing every chapter. This list will help you revise and memorise key elements from all chapters of your JEE Main Chemistry syllabus. Make a habit of solving Organic Chemistry questions for 30 – 45 minutes in your daily study routine. 

JEE Main Chemistry Syllabus preparation tips for excelling in Inorganic Chemistry

  • Class 12 Chemistry has 50% of chapters from Inorganic Chemistry. Inorganic Chemistry from the JEE Main Chemistry syllabus involves memorising various facts and exceptions versus understanding core concepts. This makes it difficult for students to prepare, and it generally gets neglected compared to Organic Chemistry.
  • More than half the paper has questions coming from Inorganic Chemistry. Experts advise students to have a strategy to help them revise Inorganic Chemistry concepts and exceptions daily. This will help them prepare better and score better against other candidates participating in the exam.
  • You can rely on NCERT textbooks for JEE Main Chemistry syllabus and have 2-3 more reference books. JEE Main exam toppers suggest books from J.D. Lee and OP Tandon. For problem-solving, you should refer to VK Jaiswal’s book “Problems in Inorganic Chemistry.
  • Considering that a lot has to be memorised, the study plan and revision strategy should be similar. Based on your liking, you can either use highlighters to mark important sections or keep a notebook where you jot down important points, reactions, exceptions, etc., for your revision later. Many students have found the use of sticky notes also to be helpful. Whichever strategy you use, the idea is for you to quickly browse through the critical points during your daily JEE Main Chemistry syllabus revision routine. 
  • Solving past problems is always beneficial. Keeping notes while solving problems will help you better understand the exam and question pattern. 
  • Create sheets and charts with a list of all essential reactions and exceptions from redox chapters, periodic tables, salt analysis, etc. Put them up on a wall to continuously see and memorise them.
  • Regular study is crucial for developing strength in Inorganic Chemistry. Don’t leave this section for the last moment. A simple plan is to daily study the chapters taught in your school and then utilise weekends to revise the same chapters.
  • Once you have completed the JEE Main Chemistry syllabus, start with 1 hour of revision for Inorganic Chemistry chapters, emphasising reactions and exceptions memorisation every day. Later it will start taking less time, around 30-45 min. Many questions come from reactions and exceptions, so cover this section adequately to score higher marks.

Other Generic  JEE Main Preparation Tips:=
