Correct increasing order for the wavelength of absorption in the visible region for the complexes of `Co^(3+)` is:A. `[Co(H_(2)O)_(6)]^(3+),[Co(en)_(3)]^(3+),[Co(NH_(3))_(6)]^(3+)`B. `[Co(H_(2)O)_(6)]^(3+),[Co(NH_(3))_(6)]^(3+),[Co(en)_(3)]^(3+)`C. `[Co(NH_(3))_(6)]^(3+),[Co(en)_(3)]^(3+),[Co(H_(2)O)_(6)]^(3+)`D. `[Co(en)_(3)]^(3+),[Co(NH_(3))_(6)]^(3+),[Co(H_(2)O)_(6)]^(3+)` |

Answer» Correct Answer - D `[epsilon_(a) prop (1)/(lambda _(a))]` ,brgt where `epsilon_(a) implies ` abosrbed energy ( splitting energy ) ` lambda_(a) implies ` absorbed wavelength `H_(2)O lt NH_(3) lt en` ligand strength `uarr` splitting energy `uarr` so absorbed `lambda darr` |
