Chemistry - Chemical Bonding and Molecular Structure

Practise 139 NEET previous year questions on Chemical Bonding and Molecular Structure, compiled from papers spanning 2002 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEET tests.

Chemical Bonding and Molecular Structure has been asked in 25 of the 39 years of NEET papers analysed (1988–2026), with 139 questions in all. 34% of them were easy, 57% moderate and 9% tough. Most of its questions came from 2013, with 11 questions that year. In the last three years (2024–2026) it had 14 questions across 13 papers, about 1.1 per paper.

The chapter's 9 topics are not weighted equally: Hybridisation and VSEPR Theory (64 questions, 46%), Molecular Orbital Theory (30 questions, 22%), and Covalent and Co-ordinate Bonding (14 questions, 10%) have been asked the most. Hybridisation and VSEPR Theory has also led over the last five years, with 9 questions. Molecular Orbital Theory has produced the most tough questions (9).
