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), (iii) and (iv)
B. (i), (ii) and (iv)
C. (ii) and (iv)
D. only (ii)

Answer

A

Explanation

Hence, orientation of ligands determine asymmetric nature of the complex.
