In the JEE Main exam, the most frequently asked subtopics from Coordination Compounds include isomerism, magnetic moment, nomenclature, and bonding. This section typically features a mix of multiple-choice questions and short numerical problems each year, carrying 4-8 marks.
- The NCERT Chemistry Book is sufficient for building concepts in Coordination Compounds.
- For numerical practice for JEE Main, you can refer to P. Bahadur’s Inorganic Chemistry.
- For better understanding, students must complete a few chapters, such as Chemical Bonding, Atomic Structure, and d & f-block elements, before Coordination Compounds.

Ques: Does JEE Main repeat the same type of Coordination Compounds questions?
Ans: In Chemistry, the pattern of questions from the Coordination Compounds chapter repeats every year, but the questions themselves are not the same.
Reddit & Student Insights: What Aspirants Say About Coordination Compounds
If you want to master the topics of coordination compounds, you need to have a good understanding of a few chapters, such as Chemical bonding, atomic structure, hybridisation, etc. This was shared by a user on Reddit, who wrote:
- “If you don't know the structure of a particular compound, then that's a different thing, but I've done lots of advanced problems in those chapters, and they all revolve around lone pairs, hybridisation, structure, and shape, etc”.

Another candidate, while talking about the weightage of the Coordination Compounds chapter in the JEE Main exam, said,
- “ 3 questions from Coordination Compounds. Yes. And OC was less, PC had more weightage. Definitely harder than 22s1”.

How to Prepare Coordination Compounds for JEE Main 2026 (Expert Strategy)
- Concept clarity first (NCERT reference): Read NCERT Class 12 chapter 9 thoroughly (2-3 times); focus on examples, tables (spectrochemical series), and back exercises.
- Formula & constants list: Memorise spectrochemical series, hybridization-gerometry table, spin formula μ = √[n(n+2)] BM, EAN rule.
- PYQs (minimum years to attempt): Solve the last 10-15 years PYQs(focus on 2020-2025 for recent trends).
- Chapter-wise MCQs target (number): 200-300 MCQs (including topic-wise from coaching modules).
- Last week's revision approach: Quick formula sheet review + 50 high-level PYQs + isomerism & CFT quick tests daily.
