$K_3[Co(C_2O_4)_3]$ || $+3$ || $t_{2g}^6 e_g^0$

Vedclass · Answer

(A) Let us evaluate each complex:$A$. $K_3[Co(C_2O_4)_3]$: $Co$ is in $+3$ oxidation state $(d^6)$. $C_2O_4^{2-}$ is a strong field ligand,so it causes pairing. Configuration: $t_{2g}^6 e_g^0$. (Correctly matched)$B$. $(NH_4)_2[CoF_4]$: $Co$ is in $+2$ oxidation state $(d^7)$. $F^-$ is a weak field ligand. Configuration: $t_{2g}^5 e_g^2$. (Correctly matched)$C$. $Cis-[Cr(en)_2Cl_2]Cl$: $Cr$ is in $+3$ oxidation state $(d^3)$. Configuration: $t_{2g}^3 e_g^0$. (Correctly matched)$D$. $[Mn(H_2O)_6]SO_4$: $Mn$ is in $+2$ oxidation state $(d^5)$. $H_2O$ is a weak field ligand. Configuration: $t_{2g}^3 e_g^2$. (Correctly matched)Upon re-evaluation,all options provided are correctly matched. However,if we look for the most common error in such questions,sometimes the configuration for $Co(II)$ in tetrahedral fields is written differently. Given the options,all are technically correct based on Crystal Field Theory.

Which of the following is an incorrectly matched complex?
