1.	Which of the following will show optical isomerism? .A. (a) `[Cu(NH_3)_4]^(2+)`B. (b) `[ZnCl_4]^(2-)`C. (c) `[Cr(C_2O_4)_3]^(3-)`D. (d) `[Co(CN)_6]^(3-)`
Answer» Correct Answer - C Optical isomerism is very common in octahedral complexes having general formula `[A_(A_2B_2C_2)]^(n-)`, `[M_((A A)_3)]^(n-)`, `[M_((A A)_2AB)]^(n-)` and `[M_((AB)_3)]^(n-)` where A A is symmetrical bidenate ligand like `underset(COO^-)underset(\|)(COO)^-` and AB is unsymmetrical bidentate ligand.
