The correct option is D They are formed based on Xe/F2 ratio
Preparation of xenon fluorides:
Xenon forms three binary fluorides, namely XeF2, XeF4, and XeF6, by the direct reaction of elements under appropriate experimental conditions. The products formed depends on the Xe/F2 ratio.
Properties of xenon fluorides (XeF2,XeF4,XeF6):
1. Colourless crystalline solids
2. They are readily hydrolysed even by traces of water
3. powerful fluorinating agents
