The energies of `d_(xy) and d_(z)^(2)` orbits in octahedral and tetrahedral transition metal complexes are such that-

Options

A. `E(d_(xy)) gt E (d_(z)^(2))` in both tetrahedral and octahedral complexes
B. `E(d_(xy)) lt E (d_(z)^(2))` in both tetrahedral and octahedral complexes
C. `E(d_(xy)) gt E (d_(z)^(2))` in tetrahedral bt `E(d_(xy)) lt E (d_(z)^(2))` in octahedral complexes
D. `E(d_(xy)) lt E (d_(z)^(2))` in tetrahedral bt `E(d_(xy)) gt E (d_(z)^(2))` in octahedral complexes

Answer

C

Explanation

Energy of `d_(z^(2))` is greater than `d_(xy)` in case of octahedral crystal field while energy of `d_(z^(2))` is less than `d_(xy)` in case of tetrahedral splitting
