Vedclass · Answer

(B) $CN^{-}$ is a strong field ligand according to the spectrochemical series.
Strong field ligands cause a large splitting of $d$-orbitals ($\Delta_o > P$,where $P$ is the pairing energy).
Due to this large splitting,electrons prefer to pair up in the lower energy $t_{2g}$ orbitals rather than occupying the higher energy $e_g$ orbitals.
Therefore,complexes containing $CN^{-}$ ligands are generally low spin complexes.

$CN^{-}$ ligand containing complexes are generally ...... .
