The compound `Co(en)_(2)(NO_(2))_(2)CI` has been prepared in these isomeric forms `A,B` and `C` A does not react with `AgNO_(3)` or (en) and is optically inactive `B` reacts with `AgNO_(3)` but not with `(en)` and is optically inactive `C` is optically active and reacts with both `AgNO_(3)` and (en) identify each of these isomeric forms and draw their structures .

trans isomer of the complex [Co(en)_2Cl_2]^+ is optically inactive. Why ?

Find the sum of optically active isomers of both [Pt(gly)_(2)Cl_(2)]" and "[Co(en)_(2)Cl_(2)] .
