The crystal field stabilization energy for a high spin $d^4$ octahedral complex is:

State the limitations of crystal field theory $(CFT)$.

For an octahedral complex,which of the following $d-$electronic configuration will give the maximum magnitude of crystal field stabilization energy,in terms of $\Delta_{o}$?

What will be the correct order for the wavelengths of absorption in the visible region for the following complexes: $[Ni(NO_{2})_{6}]^{4-}, [Ni(NH_{3})_{6}]^{2+}, [Ni(H_{2}O)_{6}]^{2+}$?

The degenerate orbitals of $[Cr(H_2O)_6]^{3+}$ are
