Vedclass · Answer

(B) $1$. In the complex ion $[Co(C_2O_4)_3]^{3-}$,the central metal atom is $Co^{3+}$.$2$. The atomic number of $Co$ is $27$,so the electronic configuration of $Co^{3+}$ is $[Ar] 3d^6$.$3$. The ligand $C_2O_4^{2-}$ (oxalate) is a strong field ligand,which causes pairing of electrons in the $3d$ orbitals.$4$. Due to the presence of a strong field ligand,the $6$ electrons in the $3d$ orbitals pair up to occupy $3$ orbitals,leaving $2$ empty $3d$ orbitals.$5$. These $2$ empty $3d$ orbitals,along with one $4s$ and three $4p$ orbitals,undergo $d^2sp^3$ hybridization to form $6$ equivalent hybrid orbitals to accommodate $6$ pairs of electrons from $3$ bidentate oxalate ligands.

The complex ion $[Co(C_2O_4)_3]^{3-}$ has which of the following hybridizations?
