Question

The optically active coordination complex ion among the following is (A) trans [Co(en)2Cl2]+  (B) cis [Co(en)(NH3)2Cl2]+  (C)  [Co(NH3)6]3+  (D)  [Fe(CN6)]3-

Usually optical isomerism is exhibited by

[M (aa)_{3}]

or

[M (aa)_{2} X_{2}]

or

[M (aa) X_{2} 1/2]

type complexes.
(Here

M =

metal atom,

aa =

bidentate ligand

X

, and

Y =

unidentate ligand).
Hence,

c i s [C o (e n (N H_{3})_{2} C l_{2}]^{+}

exhibits optical isomerism. Its optically active forms are as:
Only cis form of tetrahedral complexes of the type

[M (aa)_{2 \times 2}]^{+}

is optically active.
