Crystal field theory considers purely ionic bond between metal and ligand. The five d-orbitals in an isolated gaseous metal are degenerate. The degeneracy of the d-orbitals is lost in prsence of ligand which is known as splitting of d-orbitals.
Calculate crystal field stabilization energy in `[Co(C_(2)O_(4))_(3)]^(3-)` in terms of `Delta_(0)`

Options

A. `-2.4 Delta_(0)`
B. `+2.4 Delta_(0)`
C. `-3.6 Delta_(0)`
D. `-1.8 Delta_(0)`

Answer

A

Explanation

`d^(6) to t_(2g)^(2,2,2)eg^(0,0)`
CFSE`=-0.4xx6Delta_(0)=-2.4Delta_(0)`
