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

Text Solution

Verified by Experts

Xenon forms the binary fluorides `XeF_(2),XeF_(4),XeF_(6)` as follows. These are formed by direct combination of Xe and `F_(2)`.
`underset(("Xenon in excess"))(Xe+F_(2))underset("1 bar")overset(673" K")toXeF_(2)`
`underset((1:5" ratio"))(Xe+2F_(2))underset(4" bar")overset(873"K")toXeF_(4)`
`underset((1:20" ratio"))(Xe+3F_(2))underset(60-70" bar")overset(573" K")toXeF_(6)`
