What is the CORRECT electronic configuration of the central atom in \( \text{K}_4[\text{Fe(CN)}_6] \) based on crystal field theory?

  1. A
    \( t_{2\text{g}}^6 e_{\text{g}}^0 \)
  2. B
    \( e^3 t_2^3 \)
  3. C
    \( e^4 t_2^2 \)
  4. D
    \( t_{2\text{g}}^4 e_{\text{g}}^2 \)
View Answer & Solution

Correct answer · Option A

\( t_{2\text{g}}^6 e_{\text{g}}^0 \)

Explanation

In \( [\text{Fe(CN)}_6]^{4-} \), Fe is in \( +2 \) oxidation state (\( 3d^6 \)). Since \( \text{CN}^- \) is a strong field ligand, pairing occurs, giving \( t_{2\text{g}}^6 e_{\text{g}}^0 \).
