Vedclass · Answer

(D) Facial $(fac)$ and meridional $(mer)$ isomerism is a specific type of geometric isomerism observed in octahedral complexes with the general formula $MA_3B_3$.In this type of isomerism, three identical ligands occupy either one face of the octahedron ($fac$-isomer) or a plane passing through the metal atom ($mer$-isomer).For the given complex $[Co(NH_3)_x(NO_2)_y]$, to exhibit $fac$ and $mer$ isomerism, the coordination number must be $6$ and the stoichiometry must match the $MA_3B_3$ pattern.Therefore, $x$ must be $3$ and $y$ must be $3$, resulting in the complex $[Co(NH_3)_3(NO_2)_3]$.

If $[Co(NH_3)_x(NO_2)_y]$ shows facial and meridional isomers, identify the values of $x$ and $y$.
