Types of redox reactions

Which one of the following is not prepared from halide by chemical oxidation process


F2 + 2KX → 2KF + X2
Oxidizing power of F2 > Cl2 > Br2 > I2
No other halogen can oxidize F- to F2
In fact strongest oxidizing agent is F2 (after perxenic acid)
So it is not possible to prapare F2 by Oxidation of F-.

It is prepared by electrolytic oxidation of ion using fused KHF2
