Vedclass · Answer

(C) The complex is $[Co(AB)_2Cl_2]^{-}$,where $AB$ is an unsymmetrical bidentate ligand $(H_2NCH_2CH_2O^{-})$. Here,$A$ represents the $N$ donor atom and $B$ represents the $O$ donor atom. For an octahedral complex of the type $[M(AB)_2X_2]$,the possible geometric isomers are: $1$. Trans-$Cl$,Trans-$A$,Trans-$B$ $2$. Trans-$Cl$,Cis-$A$,Cis-$B$ $3$. Cis-$Cl$,Trans-$A$,Cis-$B$ $4$. Cis-$Cl$,Cis-$A$,Trans-$B$ $5$. Cis-$Cl$,Cis-$A$,Cis-$B$ Thus,there are $5$ possible geometric isomers.

Complexes	No. of unpaired electrons
$A. [CrF_6]^{4-}$	$P. 5$
$B. [MnF_6]^{4-}$	$Q. 2$
$C. [Cr(CN)_6]^{4-}$	$R. 1$
$D. [Mn(CN)_6]^{4-}$	$S. 4$
