Which of the following properties is/are same in: (I) [ CrCl ₆ ]³⁻ (II) [ Cr ( H ₂ O )₆ ]³⁺ (III) [ Cr ( NH ₃ )₆ ]³⁺ (IV) [ Cr ( NH ₃ )₆ ]³⁻

Options

  1. AMagnetic moment
  2. BEAN of central metal
  3. CMagnitude of splitting energy
  4. DColour

Correct answer

B. EAN of central metal

Step-by-step solution

Cr ³⁺, d ^3 configuration shows same number paired e ⁻ and EAN but strength of all ligands are different so does not slow same colour and splitting.
