Fe CN 6 3 - should be an inner orbital complex. Ignoring the pairing energy, the value of crystal field stabilization energy for this complex is - _____ Δ 0 .

Correct answer

0

Step-by-step solution

Fe CN 6 3 - In this the central metal Fe is in +3 oxidation state. And CN - is strong field ligand so, it will form inner orbital complex. Electronic configuration in Fe 3 + : d 5 Electronic configuration for inner orbital complex: t 5 2 g   e 0 g CFSE = 5 - 0 . 4 Δ 0 = - 2 . 0 Δ 0 So, final answer will be = 2
