Chemistry - Coordination Compounds

Practise 105 NEET previous year questions on Coordination Compounds, 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.

Coordination Compounds has been asked in 25 of the 39 years of NEET papers analysed (1988–2026), with 105 questions in all. 38% of them were easy, 48% moderate and 14% tough. Most of its questions came from 2026, with 9 questions that year. In the last three years (2024–2026) it had 19 questions across 13 papers, about 1.5 per paper.

The chapter's 7 topics are not weighted equally: Werner's theory and Valence Bond Theory (31 questions, 30%), Terminology of coordination compounds (20 questions, 19%), and Isomerism of coordination compounds (20 questions, 19%) have been asked the most. Over the last five years the most frequent topics have been Terminology of coordination compounds (10), Isomerism of coordination compounds (7), and Werner's theory and Valence Bond Theory (5). Werner's theory and Valence Bond Theory has produced the most tough questions (5).
