Which of the following reacts with `AsF_(3)` in liquid `BrF_(3)`?

Options

A. `XeF_(6)` only
B. `XeF_(6)` and `XeF_(4)`
C. `XeF_(2)` and `XeF_(6)`
D. `XeF_(6)` and `XeF_(2)`

Answer

C

Explanation

`XeF_6` and `XeF_2` is a `F^(-)` donor. It reacts with `PF_5, AsF_5` and `SbF_5` in presence of covalent solvent such as `BrF_3`.
`XeF_(2) + 2AsF_(5) to [XeF]^(+) + [As_(2)F_(11)]^(-)`
`XeF_(6) + AsF_(5) to [XeF]^(+) + [AsF_(6)]^(-)`
