Crystal field splitting energies for octahedral \(\left(\Delta_0\right)\) and tetrahedral \(\left(\Delta_t\right)\) geometries caused by the same ligands are related through the expression
- A \(\Delta_0=\Delta_t\)
- B \(4 \Delta_0=9 \Delta_1\)
- C \(9 \Delta_0=4 \Delta_1\)
- D \(\Delta_0=2 \Delta_1\)
Answer & Solution
Correct Answer
(B) \(4 \Delta_0=9 \Delta_1\)
Step-by-step Solution
Detailed explanation
Octahedral splitting energy \(\left(\Delta_0\right)\) and tetrahedral splitting energy \(\left(\Delta_t\right)\). For same ligands \[ \begin{aligned} \Delta_t & =\frac{4}{9} \Delta_0 \\ 9 \Delta_t & =4 \Delta_0 \end{aligned} \]
