The colour of the transition metal ions is//are due to:A. d-d transition of electrons in presence of ligandsB. charge transfer from ligand to metal ion.C. change in the geometryD. Polarisation of anion by cation |
|
Answer» Correct Answer - ABD (A) The colour of the transition metal ion/compound is attributed to d-d transition of electrons e.g. in `[Cu(CN_(3))_(4]^(2+)`. Charge transger spectrum e.g. in `MnO_(4)^(-)`(no. d electron present). The colour change is not because of change in the geometry of the molecules. Yellow colour of the `Agl` is due to the polarisation of `l^(-)` by `ag^(+)`. |
