Mn exhibits large number of oxidation states in its compounds. Which is the highest oxidation state?Name an industrially important compound you have studied in which Mn is in its highest oxidation state. How is that compound manufactured?

Answer»

In KMnO4, Mn exhibits the highest oxidation state of +7.

Oxygen and fluorine act as strong oxidising agents because of their high electronegativities and small sizes. Hence, they bring out the highest oxidation states from the transition metals. In other words, a transition metal exhibits oxidation states in oxides and fluorides. For example, in OsF6 and V2O5, the oxidation states of Os and V are + 6 and respectively.
