Vedclass · Answer

(B) The $CN^{-}$ ligand is a strong field ligand according to the spectrochemical series. Strong field ligands cause a large crystal field splitting energy $(\Delta_o)$. Because $\Delta_o$ is large,electrons prefer to pair up in the lower energy $t_{2g}$ orbitals rather than occupying the higher energy $e_g$ orbitals. This pairing of electrons results in a lower number of unpaired electrons,which characterizes a low spin complex.
