Carbon donor ligands are strong ligands and usually form low spin complexes. Among the complexes given below,select the high spin complex.

The correct increasing order for the wavelengths of absorption in the visible region for the complexes of $Co^{3+}$ is:

Arrange the following ligands in the order of increasing field strength:
$H_2O$ $(I)$,$CO$ $(II)$,$NH_3$ $(III)$,$I^{-}$ $(IV)$,$F^{-}$ $(V)$

Using crystal field theory,draw energy level diagrams,write the electronic configuration of the central metal atom/ion,and determine the magnetic moment value for the following:
$(i)$ $[CoF_{6}]^{3-}, [Co(H_{2}O)_{6}]^{2+}, [Co(CN)_{6}]^{3-}$
$(ii)$ $[FeF_{6}]^{3-}, [Fe(H_{2}O)_{6}]^{2+}, [Fe(CN)_{6}]^{4-}$

Complexes with $CN^{-}$ ligands are generally .......

Crystal field stabilization energy for complex $[Co(CN)_6]^{3-}$ will be
