JEE Main 2026 Chemistry question
Match List-I with List-II. List-I (Chromium (III) Complexes) (en = ethylene diamine): A. [Cr(CN)₆]³⁻ B. [CrF₆]³⁻ C. [Cr(H₂O)₆]³⁺ D. [Cr(en)₃]³⁺ List-II (Δ₀ in cm⁻¹): I. 15,060 II. 17,400 III. 22,300 IV. 26,600 Choose the correct answer from the options given below:
Answer: (D)
Solution
Field strength order F⁻ < H₂O < en < CN⁻ gives increasing Δ₀: CrF₆³⁻
