Which of the following is the strongest field ligand?

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

The $\Delta_0$ of a coordination complex of a metal ion $(3d^1)$ is $1000 \ kJ \ mol^{-1}$. If the energy of $t_{2g}$ orbitals is $-400 \ kJ \ mol^{-1}$,the energy (in $kJ \ mol^{-1}$) of $e_g$ orbitals is

The electron distribution in $d^{n}$ coordination complexes depends on the magnitude of crystal field splitting,$(\Delta_{0})$ and pairing energy $(P).$ The condition which favours the formation of high spin complexes is

Which of the following order of $CFSE$ is incorrect?

The correct order for wavelengths of light absorbed in the complex ions $[CoCl(NH_{3})_{5}]^{2+}$, $[Co(NH_{3})_{6}]^{3+}$ and $[Co(CN)_{6}]^{3-}$ is
