Which one of the transittion metal ions is coloured in aqueous solution?A. `Cu^(+()`B. `Zn^(2+)`C. `Sc^(3+)`D. `V^(4+)` |
|
Answer» Correct Answer - D Valence shell electron configuration of `Cu^(+) is [Ar]^(18) 3d^(10),so n=0` (B) Valence shell electron configuration of `Zn^(2+) is [Ar]^(18) 3d^(10),so n=0` (C ) Valence shell electron configuration of `SC^(3+) is [Ar]^(18) 3d^(0),so n=0` (D) Valence shell electron configuration of `V^(4+) is [Ar]^(18) 3d^(1),so n=1` As `V^(4+)` has one unpaired electrons and so in presence of water as ligand it will undergo d-d transition of electrons. Hence `V^(4+)` ions will produce colour in the solution |
