D f-f transition only
CUET Chemistry
Why does [CoF₆]³⁻ have a different colour than [Co(CN)₆]³⁻?
A They have different geometries
B F⁻ and CN⁻ cause different crystal field splitting (Δ₀), leading to absorption of different wavelengths
C Co has different oxidation states in the two complexes
D One is paramagnetic and the other is diamagnetic, which affects colour
