Vedclass · Answer

(C) Geometrical isomerism in coordination complexes occurs when ligands can be arranged in different spatial configurations (e.g.,$cis$ and $trans$).For octahedral complexes of the type $[MA_5B]$,geometrical isomerism is not possible because all positions are equivalent relative to the unique ligand $B$.In the complex $[Co(NH_3)_5NO_2]Cl_2$,there are five identical $NH_3$ ligands and one $NO_2$ ligand. Since there is no possibility of changing the relative positions of the ligands to create distinct isomers,it does not show geometrical isomerism.In contrast,$[Cr(NH_3)_4Cl_2]Cl$,$[Co(en)_2Cl_2]Cl$,and $[Pt(NH_3)_2Cl_2]$ all possess ligands that can be arranged in $cis$ and $trans$ configurations.
