Question

The crystal field splitting energy for octahedral $\left({\Delta }_{\circ }\right)$ and tetrahedral $\left({\Delta }_t\right)$ complexes is related as:

• A. ${\Delta }_t=\frac{4}{9}{\Delta }_{\circ }$
• B. ${\Delta }_t=\frac{1}{2}{\Delta }_{\circ }$
• C. ${\Delta }_{\circ }=-2{\Delta }_t$
• D. ${\Delta }_{\circ }=-\frac{4}{9}{\Delta }_t$

Answer 1

The correct option is A ${\Delta }_t=\frac{4}{9}{\Delta }_{\circ }$

$[{\Delta }_{sq}>{\Delta }_0>{\Delta }_t]$

${\Delta }_{sq}=\frac{4}{3}{\Delta }_0$ ${\Delta }_t=\frac{4}{9}{\Delta }_0$
