lf the crystal filed splitting energy for octahedral complexes is ${\Delta }_0$ and for tetrahedral complexes is $\Delta t$, the two are related as

• A

  ${\mathrm{\Delta }}_t=\frac{4}{9}{\mathrm{\Delta }}_{\mathrm{o}}$

• B

  ${\mathrm{\Delta }}_t=\frac{1}{2}{\mathrm{\Delta }}_{\mathrm{o}}$

• C

  ${\mathrm{\Delta }}_{\mathrm{o}}=\frac{1}{2}{\mathrm{\Delta }}_t$

• D

  ${\mathrm{\Delta }}_{\mathrm{o}}=\frac{4}{9}{\mathrm{\Delta }}_t$
