Xenon hexa fluoride reacts with potassiu...

Xenon hexa fluoride reacts with potassium fluoride to yield

A

`[XeF_(5)]^(+)[KF_(2)]^(-)`

B

`K^(+)[XeF_(7)]^(-)`

C

`XeF_(4)`

D

`[XeF_(4)]^(2+)[KF_(2)]^(3-)`

Text Solution

Verified by Experts

The correct Answer is:
B
KF is a fluoride ion donor, hence it reacts with `XeF_(6)` to give a fluoroanion.
`XeF_(6) + KF rarr K^(+) [XeF_(7)]^(-)`

The noble gases are chemically inert due to high ionization enthalpy, positive electron gains enthalpy and presence of completely filled orbitals. However, Xe forms a number of compounds such as XePtF_(6) XeF_(2), XeF_(4), XeF_(6) and a number of xenon oxides and oxy fluorides. Xenon fluorides react with fluoride ion acceptors such as PF_(5), AsF_(5), SbF_(3) etc. to form cationic species but with fluoride ion donors such as alkali metal fluorides they forms anionic fluoroanions. They are also hydrolysed by water but their reactivity increases with oxidation state of Xe. The shape and hybridisation of some Xenon oxygen fluorides are given. Select the wrong answer.
