How are xenon fluorides XeF_(2) , XeF_(4) and XeF_(6) obtained?

How are xenon fluorides XeF_(2),XeF_(4) and XeF_(6) obtained?

In xenon fluorides most reactive in XeF_(6) , XeF_(4) and XeF_(2) is

In XeF_(2),XeF_(4) and XeF_(6)(g) the number of lone pairs on Xe respectively are :

A : XeF_(6) on the reaction with RbF gives Rb[XeF_(7)] R : XeF_(6) is non - reactive .

How are xenon fluorides, XeF_(2), XeF_(4) " and " XeF_(6) prepared ? Describe their molecular shapes.

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. When XeF_(4) is treated with water, it forms ?
