Three complexes,[CoCl(NH_3)_5]^2+ (I), [Co(NH_3)_5 H_2O]^3+(II) and [Co(NH_3)_6]^3+ (III) absorb light in the visible region. The correct order of the wavelength of light absorbed by them is :

Question

Accepted Answer

Correct answer: C. (c) absorbed depends on strength of ligand. For stronger ligand, Δ_0 will be higher, λ will be lesser. NH_3 > H_2O > Cl^– decreasing order of strength of ligand.
