[Ti(H_(2)O)_(6)]^(2+) is coloured whereas [Sc(H_(2)O)_(6)]^(3+) s colourless, though it is a transition metal complex. Explain the observation. |
| Answer» SOLUTION :Tit has one electron in the d-orbital `(3d^(1))` which can absorb ENERGY corresponding to yellow wavelength and jump from LOWER energy LEVEL to higher energy level. But `Sc^(3+)`has no electron in d-orbital | |
