he following complexes
(\underset{\large }{\left[\mathrm{CoCl}\left(\mathrm{NH}_{3}\right)_5\right]^{2+}},\underset{\large \text{(B)}}{\left[\mathrm{Co}(\mathrm{CN})_6\right]^{3-}},\underset{\large \text{(C)}}{\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_5\left(\mathrm{H}_{2} \mathrm{O}\right)\right]^{3+}},\underset{\large \text{(D)}}{\left[\mathrm{Cu}\left(\mathrm{H}_{2} \mathrm{O}\right)_4\right]^{2+}})
The correct order of A, B, C and D in terms of wavenumber of light absorbed is :
Options
- AC D A B
- B(\mathrm{B} < \mathrm{C} < \mathrm{A} < \mathrm{D})
- CA C B D
- DD A C B
Correct answer
D. D A C B
