Vedclass · Answer

(B) Geometrical isomerism in coordination compounds requires different spatial arrangements of ligands around the central metal atom.For octahedral complexes of the type $[MA_5B]$,geometrical isomerism is not possible because all positions are equivalent relative to the single $B$ ligand.In the complex $[Cr(NH_3)_5Cl]Cl_2$,the coordination sphere is $[Cr(NH_3)_5Cl]^{+2}$. This is an $MA_5B$ type complex,where $M = Cr$,$A = NH_3$,and $B = Cl$.Since there is only one $Cl$ ligand,it cannot be placed in different positions (cis or trans) relative to other ligands,hence it does not show geometrical isomerism.Other options like $[Pt(NH_3)_2(H_2O)_2]^{+2}$ ($MA_2B_2$ type),$[Co(en)_2Cl_2]Cl$ ($MA_2B_2$ type),and $[Co(NH_3)_4Cl_2]Cl$ ($MA_4B_2$ type) all exhibit geometrical isomerism.
