JEE Main Chemistry Chapter-wise PYQs: Chemistry is one of the three main subjects in JEE Main and plays a big role in a student’s overall score. A strong grip on Chemistry can greatly increase the chances of getting a good All India Rank (AIR). Many students find this subject tough because it requires clear knowledge of reactions, mechanisms, and formulas, as well as the ability to solve problems by applying these concepts. But with regular practice and the right study plan, Chemistry can become one of the most scoring subjects in the exam. In JEE Main, Chemistry questions check both your understanding of concepts and your ability to apply formulas quickly. If you master this subject, you can solve problems faster and with better accuracy. A very effective way to prepare is by solving JEE Main Chemistry Previous Year Questions (PYQs). These questions help you understand the exam pattern, the difficulty level, and the topics that are asked often. Practising PYQs also builds confidence and improves your understanding of reactions. To support students, this article provides a free PDF of JEE Main Chemistry previous year questions with solutions.

JEE Main Chemistry Exam Pattern

Why Solve JEE Main Chemistry Previous Year Questions?

Solving previous years’ Chemistry questions from JEE Main is one of the best ways to prepare for the exam. It shows you the type of questions that are usually asked and helps you understand which chapters are most important. By practising these questions regularly, you can improve your speed, accuracy, and confidence in Chemistry. It also makes you familiar with the exam pattern so that nothing feels new on the actual exam day.

  • Understand the exam pattern: Know the type of questions asked, such as MCQs and numerical value questions in Chemistry.
  • Familiarity with repeated concepts: Some reactions, concepts, and formulas are repeated often. PYQs help you identify these high-weightage areas.
  • Improve speed and accuracy: Regular practice makes you quicker in solving chemical equations, reaction-based questions, and numerical problems.
  • Check your preparation: Solving real exam questions lets you judge how well you understand Chemistry and where you need to improve.
  • Improve time management: PYQs teach you how much time to spend on physical, organic, and inorganic Chemistry questions during the exam.

How to Solve JEE Main Chemistry Previous Year Questions Effectively

Practising previous year questions (PYQs) for JEE Main Chemistry is a very effective way to prepare. It helps you understand the type and difficulty level of questions. But just solving them is not enough-you need the right strategy to get the maximum benefit. Solve questions in a timed manner, review your mistakes, learn the correct methods, and revise regularly to improve your score.

  • Solve in exam-like conditions, set a timer and avoid distractions.
  • After each chapter, check where you went wrong and understand the concept properly.
  • Focus on high-weightage units like Chemical Bonding, Coordination Compounds, Thermodynamics, and Organic Chemistry.
  • Master chapter-wise PYQs first. Once confident, move on to mixed and full-length tests.
  • Check solutions and understand the best way to solve tricky questions.
  • Practice solving previous year questions in a time-bound manner to improve speed and accuracy.
