A) Ions of d-block elements are coloured due to d-d transition
B) lons of\[f-\]block elements are coloured due to\[f-f\]transition
C) \[{{[Sc{{({{H}_{2}}O)}_{6}}]}^{3+}},{{[Ti{{({{H}_{2}}O)}_{6}}]}^{4+}}\]are coloured complexes
D) \[C{{u}^{+}}\] is colourless ion
Correct Answer: C
Solution :
\[S{{c}^{3+}}(3{{d}^{0}})\]and\[T{{i}^{4+}}(3{{d}^{0}})\]are colourless because they have empty\[d-\]orbitals, hence \[d-d\]transition is impossible.
