1.

which of the following sdoes not show optical isomerism ?

Answer»

`[Co(NH_(3))_(3)Cl_(3)]`
`[Co(EN)Cl_(2)(NH_(3))_(2)]^(+)`
`[Co(en)_(3)]^(3+)`
`[Co(en)_(2)Cl_(2)]^(+)`
(E = ethylenediammine)

Solution :Complexes of the type `MA_(3)b_(3)` donot show any optical isomerism. THEREFORE, `[Co(NH_(3))_(3)Cl_(3)]` will not have any optical ISOMER.
