Which one of these complex ions would absorb light with the shortest wavelength?
A) [Co(H2O)6]2+ D) [Co(CN)6]4–
B) [Co(NH3)6]2+ E) [Co(en)6]2+
Solution
Absorbing at longest wavelength means having the smallest energy difference in the orbitals.
so, F-<H2O<en<Cn-
so the answer is CN- (i was not able to read becouase of many A\'s present in the question
