Which of the following reactions is an example of a redox reaction?
Hint: In above reaction. xenon is oxidised while oxygen is reduced i.e .. it is redox reaction.)

Options

A. `XeF_(4)+O_(2)F_(2) to XeF_(6)+O_(2)`
B. `XeF_(2)+PF_(5) to [XeF]^(+)PF_(6)^(-)`
C. `XeF_(6)+H_(2)O to XeOF_(4)+2HF`
D. `XeF_(6)+2H_(2)O to XeO_(2)F_(2)+4HF`

Answer

A

Explanation

`overset(+4 -4)(XeF_(4))+overset(+2)(O_(2))overset(-2)(F_(2))to overset(+6 -6)(XeF_(6))+overset(0)(O_(2))`
In above reaction xenon is oxidised while oxygen is reduced i.e. it is redox reaction.
