Ionic and covalent bonding, lattice enthalpy, electronegativity, Fajan's rule, dipole moment, VSEPR theory, valence bond theory and hybridisation, resonance, molecular orbital theory and bond order, hydrogen bonding.
Does a high weightage mean Chemical Bonding and Molecular Structure will be asked again?
No. Weightage shows past frequency, not a promise. Use it to prioritise, and practise previous-year questions to see how the chapter is tested.

More JEE Main guides
Counts are compiled from Edurack's JEE Main last five-year analysis (2022–2026) and count questions across all shifts and sessions of each year. Because the number of shifts changes every year, trends compare each chapter's share of the paper among chapters still in the syllabus, not raw counts. Past frequency is a trend guide, not a prediction. Chapters marked "not in syllabus" are absent from NTA's JEE Main 2026 syllabus; always check the latest NTA syllabus before skipping a chapter.
