Which one of the following complexes will most likely absorb visible light?
(At nos. \(Sc = 21 , Ti = 22, V = 23, Zn = 30\))
- A \({[Sc{({H_2}O)_6}]^{3 + }}\)
- B \({[Ti{(N{H_3})_6}]^{4 + }}\)
- C \({[V{(N{H_3})_6}]^{3 + }}\)
- D \({[Zn{(N{H_3})_6}]^{2 + }}\)
Answer & Solution
Correct Answer
(C) \({[V{(N{H_3})_6}]^{3 + }}\)
Step-by-step Solution
Detailed explanation
The absorption of visible light and hence coloured nature of the transition metal cation is due to the promotion of one or more unpaired \(-\,d\,-\) electron from a lower to higher will be the number of unpaired electron higher will be the absorption in visible light. The…
