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. Both geometrical and optical isomerism are shown byA. `[Co(en)_(2)Cl_(2)]^(+)`B. `[Co(NH_(3))_(5)Cl]^(2+)`C. `[Co(NH_(3))_(4)Cl_(2)]`D. `[Cr(OX)_(3)]^(3-)`

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. Both geometrical and optical isomerism are shown byA. `[Co(en)_(2)Cl_(2)]^(+)`B. `[Co(NH_(3))_(5)Cl]^(2+)`C. `[Co(NH_(3))_(4)Cl_(2)]`D. `[Cr(OX)_(3)]^(3-)`
Answer» Correct Answer - a The compound shows both geometrical & optical isomerism.
