Vedclass · Answer

(C) $1$. $[Ni(CN)_6]^{2-}$: $Ni^{2+}$ is $d^8$. $CN^-$ is a strong field ligand,forcing pairing. It forms $d^2sp^3$ hybridization (inner orbital complex) and is diamagnetic (magnetic moment = $0$).$2$. $[Mn(NH_3)_6]^{2+}$: $Mn^{2+}$ is $d^5$. $NH_3$ is a strong field ligand,forcing pairing. It forms $d^2sp^3$ hybridization and has one unpaired electron (magnetic moment $
eq 0$).$3$. $[Co(H_2O)_6]^{3+}$: $Co^{3+}$ is $d^6$. $H_2O$ is a weak field ligand. It forms $sp^3d^2$ hybridization (outer orbital complex) and has four unpaired electrons (magnetic moment $
eq 0$).Therefore,$[Co(H_2O)_6]^{3+}$ satisfies both conditions.

Which of the following has a non-zero magnetic moment and $sp^3d^2$ hybridization?
