Which of the following will exhibit optocal isomerism ?

Answer»

`[Cr(EN)(H_(2)O)_(4)]^(3+)`
`[Cr(en)_(3)]^(3+)`
trans-`[Cr(en)(Cl_(2))(NH_(3)_(2)]^(+)`
`[Cr(NH_(3))_(6)]^(3+)`

Solution :`[Cr(en)_(3)]^(3+)` exhibit optical isomerism. When an OCTAHEDRAL complex contains three bidentate GROUPS, it SHOW optically activity and exist in two enantonmeric forms.
