Correct increasing order for the wavelength of absorption in the visible region for the complexes of Co 3+ is:(1) [Co(CN)6]3- , [Co(NH3)6]3+ , [Co(NH3)5(H2O)] 3+ [Co(NH3)5Cl]+2(2) [Co(CN)6]3- , [Co(NH3)5(H2O)]3+ [Co(NH3)5Cl]+2 [Co(NH3)6]3+ ,(3) [Co(NH3)6]3+ , [Co(CN)6]3-, [Co(NH3)5(H2O)]3+ [Co(NH3)5Cl]+2 (4) [Co(NH3)5Cl]+2 , [Co(NH3)5(H2O)]3+ , [Co(NH3)6]3+ , [Co(CN)6]3- |

Answer» Correct option (1) [Co(CN)6]3- , [Co(NH3)6]3+ , [Co(NH3)5(H2O)]3+ [Co(NH3)5Cl]+2 Explanation: Strength of ligands attached with Co3+ ion is in the order of CN- > NH3 > H2O > Cl-. So order of spliting (value of Δ0 ) will be in the same order. ∴ Wave length absorbing light α1/Δ0 |
