Question

Complex compounds(s) which is optical active and does not depend upon the orientation of the ligands around metal cation :
(i) [CoCl3(NH3)3] (ii) [Co(en)3]Cl3
(iii) [Co(C2O4)2(NH3)2]- (iv) [CrCl2(en)2]+

Prashant Kotian · Accepted Answer

Correct answer: D. [Co(en)3]3+ is always chiral regardless of orientation. For (iii) and (iv), the trans form is optically inactive, so their optical activity depends on the orientation (cis vs trans).
