Assuming it would dissolve, what you think will happen to the absorption band of MnO4 - if the ion was dissolved in acetonitrile instead of water? Briefly explain your answer
Homework Answers
As it has been mentioned in the question the molecule will dissolve in acetonitrile therefor we assume the formation of MnO4- ion here. Now talk about the color, the color f ion here is not because of d-d transition but because of the LMCT(Ligand t metal Charge Transfer) therefor has nothing to do with the solvent. Solvent may increase or decrease the density of color but can have practically no effect on the absorption band.

i) Consider the crystal field diagram for a tetrahedral complex and the relative d orbital configuration. Show the purple colour of MnO4 - cannot be from d-d transitions and briefly explain your answer. ii) Draw a simplified molecular orbital diagram (i.e. like those used for ligand field theory in lectures) to show the possible origin of the transition responsible for the purple colour of an aqueous KMnO4 solution. iii) MnO4 - ions actually have two intense transitions, one at 541...
