In disproportionation reaction, an element in one oxidation state simultaneously undergoes oxidation and reduction.

So, to take place such type of redox reaction, the element should exist in at last three oxidation states.

So that element present in the intermediate state and it can change to both higher and lower oxidation state during disproportionation reaction.

Fluorine is the most electronegative element and a strong oxidizing agent.

It does not show a positive oxidation state and does not undergo a disproportionation reaction.
