Complex compounds(s) which is optical active and does ot dpeend upon the orientation of the ligands around metal cation:
(i) `[CoCl_(3)(NH_(3))_(3)]`
(ii) `[Co(en)_(3)]Cl_(3)`
(iii) `[Co(C_(2)O_(4))_(2)(NH_(3))_(2)]^(-)`
(iv) `[CrCl_(2)(NH_(3))_(2)(en)]^(+)`

Options

A. II,IIIand Iv
B. I,Iiand Iv
C. II and Iv
D. Only II

Answer

d

Explanation

In other complexes the orientation decides whether the complex is optically active or not .
