Vedclass · Answer

(A) species responds to an external magnetic field if it is paramagnetic (contains unpaired electrons).$1.$ $[Fe(H_{2}O)_{6}]^{3+}$: $Fe^{3+}$ is $3d^{5}$. $H_{2}O$ is a weak field ligand,so electrons remain unpaired. It is paramagnetic.$2.$ $[Ni(CO)_{4}]$: $Ni$ is $3d^{8} 4s^{2}$. $CO$ is a strong field ligand,forcing pairing. It is diamagnetic.$3.$ $[Co(CN)_{6}]^{3-}$: $Co^{3+}$ is $3d^{6}$. $CN^{-}$ is a strong field ligand,forcing pairing. It is diamagnetic.$4.$ $[Ni(CN)_{4}]^{2-}$: $Ni^{2+}$ is $3d^{8}$. $CN^{-}$ is a strong field ligand,forcing pairing. It is diamagnetic.Thus,$[Fe(H_{2}O)_{6}]^{3+}$ is the only paramagnetic species.
