Current Question (ID: 18761)

Question:

$\text{The crystal field stabilization energy (CFSE) for } [\text{CoCl}_6]^{4-} \text{ is } 18000 \text{ cm}^{-1}. \text{ The CFSE for } [\text{CoCl}_4]^{2-} \text{ will be:}$

Options:

1. $6000 \text{ cm}^{-1}$
2. $16000 \text{ cm}^{-1}$
3. $18000 \text{ cm}^{-1}$
4. $8000 \text{ cm}^{-1}$

Solution:

$[\text{CoCl}_4]^{2-} \text{ is tetrahedral whereas } [\text{CoCl}_6]^{4-} \text{ is octahedral.}$ $\Delta_t = \frac{4}{9} \Delta_0$ $\Delta_t = \frac{4}{9} \times 18000 = 8000 \text{ cm}^{-1}$
