[Ti(H(2)O)(6)]^(2+) is coloured whereas ...

`[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.

Text Solution

Verified by Experts

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
