Question

The CFSE for octahedral $\text{[}{\text{CoCI}}_6{]}^{4-}\text{is}18,000{\text{cm}}^{-1}$ The CFSE for tetrahedral $\text{[}{\text{CoCI}}_4{]}^{2-}$ will be

• A. 18,000 cm⁻¹
• B. 16,000cm⁻¹
• C. 8,000cm⁻¹
• D. 20,000cm⁻¹

Answer 1

The correct option is C

8,000cm⁻¹

$△\text{t}=\frac{4}{9}{△}_0=\frac{4}{9}\times 18000=8000{\text{cm}}^{-1}$
