Which one of the ionic species will impart colour to an aqueous solution?A. `Ti^(4+)`B. `Cu^(+)`C. `Zn^(2+)`D. `Cr^(3+)` |
|
Answer» Correct Answer - D In `Ti^(4+),Cu^(+)` and `Zn^(2+)` , all have electrons paired so all the diamagnetic. `Cr^(3+)` with electrons configuration `[Ar]^(18) 3d^(3)` has three unpaired electrons. So it undergoes d-d transition of electrons in presence of ligands according to CFT and thus it is coloured. |
