Vedclass · Answer

(C) Geometrical isomerism in octahedral complexes occurs when ligands are arranged in different spatial orientations (cis and trans forms).$I$) $[Co(en)(NH_3)_2 Cl_2] Cl$: This complex has the form $[M(AA)(a)_2(b)_2]$,which exhibits geometrical isomerism.$II$) $[Co(NH_3)_4 Cl_2] Cl$: This complex has the form $[M(a)_4(b)_2]$,which exhibits cis and trans geometrical isomers.$III$) $[Co(en)_3] Cl_3$: This complex has the form $[M(AA)_3]$. It does not show geometrical isomerism because all positions are equivalent due to the symmetry of the bidentate ligands.$IV$) $[Co(en)_2 Cl_2] Br$: This complex has the form $[M(AA)_2(b)_2]$,which exhibits cis and trans geometrical isomers.Therefore,complexes $I, II,$ and $IV$ exhibit geometrical isomerism.

Which of the following complexes exhibit geometrical isomerism?
$I$) $[Co(en)(NH_3)_2 Cl_2] Cl$
$II$) $[Co(NH_3)_4 Cl_2] Cl$
$III$) $[Co(en)_3] Cl_3$
$IV$) $[Co(en)_2 Cl_2] Br$
