Vedclass · Answer

(D) $CN^-$ is a strong field ligand,while $Br^-$ and $F^-$ are weak field ligands.For $[Ni(CN)_4]^{2-}$,$Ni^{2+}$ has $d^8$ configuration. $CN^-$ causes pairing,leading to $dsp^2$ hybridization (square planar) with $0$ unpaired electrons and $\mu = 0 \ BM$.For $[MnBr_4]^{2-}$,$Mn^{2+}$ has $d^5$ configuration. $Br^-$ is a weak ligand,leading to $sp^3$ hybridization (tetrahedral) with $5$ unpaired electrons and $\mu = \sqrt{5(5+2)} = 5.9 \ BM$.For $[FeF_6]^{4-}$,$Fe^{2+}$ has $d^6$ configuration. $F^-$ is a weak ligand,leading to $sp^3d^2$ hybridization (octahedral) with $4$ unpaired electrons and $\mu = \sqrt{4(4+2)} = 4.9 \ BM$.

The geometry,hybridization,and magnetic moment of the ions $[Ni(CN)_4]^{2-}$,$[MnBr_4]^{2-}$,and $[FeF_6]^{4-}$ respectively are:
