InterviewSolution

1.	In which of the following ions , the colour is not due to d-d transition ?A. `Ti(H_(2)O)_(6)^(3+)`B. `CoF_(6)^(3+)`C. `CrO_(4)^(2-)`D. `[Cu(NH_(3))_(4)]^(2+)`
Answer» Correct Answer - C In `CrO_(4)^(2-)`, Cr is in `+6` oxidation state.It has `d^(0)` configuration .The coloure is dueto charge transfer and not due to d-d transition
