JEE Chemistry: An overview

  • Experts suggest that chemistry is a scoring subject in the JEE Main exam, with 4 tough level questions, 11 medium level questions, and 10 easy level questions. The JEE Main Chemistry Syllabus is divided into two sections: Physical Chemistry and Organic and Inorganic Chemistry. Students who are well-prepared for this subject should ideally be able to attempt the paper in 40-45 minutes.
  • Physical Chemistry covers chapters such as Some basic concepts in chemistry, Atomic structure, Chemical thermodynamics, Equilibrium, and States of matter. Inorganic Chemistry includes chapters such as Hydrogen, p-Block elements, d- & f-Block elements, s- Block elements, and Classification of elements & Periodicity in Properties. Organic Chemistry covers chapters like Purification Characterisation of Organic Compounds, Hydrocarbons, Polymers, Biomolecules, and Chemistry in Everyday Life.
  • Around 33.33% of the questions in the JEE Main exam are from the Organic Chemistry section. Students must focus on these topics and concepts, as they may appear to be difficult. Additionally, 50% weightage comes from Inorganic Chemistry sections from the Chemistry Syllabus, with questions mainly asked from exceptions and reactions, requiring more emphasis on these topics as per previous year’s analysis.
  • For JEE Main Chemistry preparation, it is recommended to refer to Chemistry NCERT CLASS 11 and CLASS 12, Objective Chemistry Vol I and II by Arihant, and another textbook of Organic Chemistry for AIPMT and all other medical examinations by Dr. OP Tandon. Objective NCERT At Your Fingertips for JEE Chemistry by MTG Editorial Board is also a useful resource. With a strong foundation in these books, students can attempt the questions with confidence and achieve a good score in the JEE Main exam.
