NEET Chemistry Ligands MCQ Question
Calculate the crystal field stabilization energy (CFSE) in terms of D_o for the high spin complex [CoF6]3-.
-0.4 D_o
-0.6 D_o
-1.2 D_o
-2.4 D_o
Correct Answer
Detailed Explanation
For a high spin d6 complex like [CoF6]3-, the CFSE is calculated as (-2/5)D_o for four t2g electrons and (+3/5)D_o for two e_g electrons, resulting in (-2/5)D_o * 4 + (+3/5)D_o * 2 = -1.2 D_o.
