Part 2.7 The reaction of alkenes with aqueous potassium manganate(VII) - oxidation to form diol alcohols
A redox reaction involving oxidation of an organic compound and the reduction of an inorganic compound.
2.7 The reaction of alkenes with aqueous potassium manganate(VII)
The half-reaction equation for the potassium manganate(VII) is ...
MnO4-(aq) + 4H+(aq) + 3e- ===> MnO2(s) + H2O(l)
The half-cell potential for this half-reaction is Eθ = +1.67 V, so the manganate(VII) ion is a strong oxidising agent.
