JEE Main 2026: Difficulty Level Trends in Chemistry

Across several January shifts, the Chemistry section was generally easy to moderate for most candidates. Students reported that questions were largely NCERT-based, with a balanced mix of conceptual and application-oriented items from physical, organic, and inorganic chemistry. Organic and inorganic topics were especially prominent alongside core chapters like coordination chemistry and thermodynamics.

JEE Main 2026: Key Topics Aspirants Should Focus On

From the patterns observed in JEE Main 2026 January papers, the following topics emerged repeatedly and have been useful for overall Chemistry preparation:

Organic Chemistry

Hydrocarbons
Amines
Biomolecules

Inorganic Chemistry

Coordination Compounds
Chemical Bonding
Ionic Equilibrium

Physical Chemistry

Thermodynamics
Electrochemistry
Solutions and Redox Reactions

Several expert analyses also note that a firm grasp of the basic concepts and NCERT syllabus helps score well in Chemistry due to the direct nature of many questions. Students preparing for upcoming shifts or future sessions should prioritise these high-weightage chapters, which have a strong record of recurring in recent exams.
