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

Answer»

`XeF_(4)+O_(2)F_(2)toXeF_(6)+O_(2)`
`XeF_(2)+PF_(5)to[XeF]^(+)PF_(6)^(-)`
`XeF_(6)+H_(2)OtoXeOF_(4)+2HF`
`XeF_(6)+2H_(2)OtoXeO_(2)F_(2)+4HF`

Solution :Reaction (B), (C) and (D) are not REDOX reaction In reaction (A), `O_(2)F_(2)` is oxidising AGENT and `XeF_(4)` is reducing agent.
