Which of the following reactions is an example of a redox reaction?

Options

A. `XeF_(2)+PF_(5)to[XeF]^(+)PF_(6)^(-)`
B. `XeF_(6)+H_(2)OtoXeOF_(4)+2HF`
C. `XeF_(6)+2H_(2)OtoXeO_(2)Fe_(2)+4HF`
D. `XeF_(4)+O_(2)F_(2)toXeF_(6)+O_(2)`

Answer

D

Explanation

Redox reaction:
`darr` Se= Decrease, `uarr` Se = Increase
`**darr` Se in oxidation Number +1 `**` Reduction
`**` Oxidizing Agent (O.A.)

`**uarr` Se in oxidation Number +2
`**` Oxidation
`**` Reducing Agent (R.A.)
`XeF_(4)` is oxidized while `O_(2)F_(2)` is reduced.
