JEE Main Chemistry Chapter-Wise Weightage 2026 FAQs
Why is knowing the chapter-wise weightage important for JEE Main Chemistry preparation?
Understanding chapter-wise weightage helps students focus on high-scoring topics, manage study time efficiently, and prepare strategically for better results.
Will the JEE Main 2026 syllabus change significantly?
NTA is expected to announce the official syllabus in November 2025. However, syllabus reductions in recent years make focusing on high-weightage chapters more crucial.
What is the best way to decide which Chemistry chapters to focus on for JEE Main 2026?
Start by focusing on chapters with historically higher weightage such as Chemical Bonding, Organic Compounds, and Coordination Chemistry, then cover the remaining topics thoroughly.
Is it necessary to cover the entire syllabus for Chemistry?
While it’s ideal to cover the entire syllabus, focusing on high-weightage chapters first ensures efficient preparation and maximizes scoring potential.
Does class XI or XII Chemistry have more questions in JEE Main?
Both classes contribute significantly, but recent trends show a fairly balanced distribution. It’s important to be strong in both for a good score.

JEE Main Chemistry Chapter Wise Weightage 2026 : Knowing the chapter-wise weightage of Chemistry is key for smart JEE Main preparation. Based on previous years’ analysis, it helps students focus on high-scoring and frequently asked topics.Although the official 2026 syllabus will be released in November, students should start early by targeting important chapters. With NTA’s recent syllabus reduction, focusing on high-weightage topics is more important than ever for efficient and strategic preparation.
JEE Main Chemistry syllabus for JEE Main 2026 is categorized into three main sections: Physical Chemistry, Inorganic Chemistry, and Organic Chemistry.
Physical Chemistry (Section A) : includes topics like Some Basic Concepts of Chemistry, Atomic Structure, Chemical Bonding and Molecular Structure, Chemical Thermodynamics, Equilibrium, Redox Reactions and Electrochemistry, Solutions and Chemical Kinetics.
Inorganic Chemistry (Section B) : covers the Classification of Elements and Periodicity in Properties, the p-block Element (Group 13 and 14), the d- and f-block Elements, and Coordination Compounds.
Organic Chemistry (Section C) : comprises Purification and Characterisation of Organic Compounds, Some Basic Principles of Organic Chemistry, Hydrocarbons, Organic Compounds Containing Halogens, Oxygen, and Nitrogen, and Principles Related to Practical Chemistry.
This structured division helps students plan their preparation effectively across all three areas of Chemistry.
The chapter-wise weightage for JEE Main 2026 is derived from a detailed analysis of past years' question paper trends. Chemistry is broadly divided into three major branches: Organic, Inorganic, and Physical Chemistry. A breakdown of chapters with the number of questions and their corresponding weightage will help students understand which topics to focus on during their preparation.
