JEE Main 2024 Chemistry question
Consider the following complex ions P = [FeF₆]³⁻ Q = [V(H₂O)₆]²⁺ R = [Fe(H₂O)₆]²⁺ The correct order of the complex ions, according to their spin only magnetic moment values (in B.M.) is :
Answer: (C)
Solution
F⁻ and H₂O are weak field ligands, so no pairing occurs. P: Fe³⁺ (d⁵) has 5 unpaired electrons, μ = √35 BM. Q:
