How many JEE Advanced questions come from Coordination Compounds?
Coordination Compounds has contributed 26 questions to Joint Entrance Examination (Advanced) papers between 2016 and 2026 — an average of about 2 questions a year. That count is measured from EByAi’s bank of 18,502 JEE Advanced questions, not estimated from a syllabus. Every one of the 26 questions carries a written, step-by-step solution, and each is tagged to Coordination Compounds within Chemistry, so you can drill this chapter across every year at once instead of hunting through paper PDFs. Practising a chapter’s full PYQ history is the fastest way to learn the patterns examiners reuse.

Question 1 · JEE Advanced 2025
The correct order of the wavelength maxima of the absorption band in the ultraviolet-visible region for the given complexes is- (A)[Co(CN) 6 ] 3− < [Co(NH 3 ) 6 ] 3+ < [Co(NH 3 ) 5 (H 2 O)] 3+ < [Co(NH 3 ) 5 (Cl)] 2+
- (B)[Co(NH 3 ) 5 (Cl)] 2+ < [Co(NH 3 ) 5 (H 2 O)] 3+ < [Co(NH 3 ) 6 ] 3+ < [Co(CN) 6 ] 3−
- (C)[Co(CN) 6 ] 3− < [Co(NH 3 ) 5 (Cl)] 2+ < [Co(NH 3 ) 5 (H 2 O)] 3+ < [Co(NH 3 ) 6 ] 3+
- (D)[Co(NH 3 ) 6 ] 3+ < [Co(CN) 6 ] 3− < [Co(NH 3 ) 5 (Cl)] 2+ < [Co(NH 3 ) 5 (H 2 O)] 3+
