Stereoisomerism arises on account of different positions and arrangement of lignads in space around the metal ion . These are classified into two types : (i) Geometrical isomerism is exhibited by octahedral and square planar complexes . (ii) Optical isomerism is shown when mirror images are non superimposable. The compound(s) that exhibi(s) geometrical isomerism is(are) :

1.	Stereoisomerism arises on account of different positions and arrangement of lignads in space around the metal ion . These are classified into two types : (i) Geometrical isomerism is exhibited by octahedral and square planar complexes . (ii) Optical isomerism is shown when mirror images are non superimposable. The compound(s) that exhibi(s) geometrical isomerism is(are) :
Answer» `[Pt(en)Cl_(2)]` `[Co(OH_(2))_(4)Cl_(2)]CL` `[Pt(en)_(2)Cl_(2)]Cl_(2)` `[Pt(NH_(3))_(2).Cl_(2)]` Solution :Both SHOW geometrical isomerism.
