The chemical reactivity of noble gases involves the loss of electrons and hence it can form compounds with highly electronegative elements like F and O. Although Xe forms several fluorides, xenone tetrafluoride is the most important among fluorides. The various compounds of xenon involve xenon in first, second or third excited states.

All the noble gases are colourless and tasteless monoatomic gases. In general, noble gases are least reactive and their inertness to chemical reactivity is attributed to the following reasons. Reactive and their inertness to chemical reactivity is attributed to the following reasons. (i)Except helium, all have completely filled ns^(2)np^(6) electronic configuration in their valence shells. (ii)All have high ionisation enthalpy and more positive electron gain enthalpy. However, a number of xenon compounds mainly with most electronegative elements like fluorine and oxygen have been synthesized under different conditions and fluorides of xenon have been used as an oxidising agent and a fluorinating agent in many of the chemical reactions Identify the correct statement with respect to XeF_(2)

Among noble gases, Xe is quite reactive and form a number of fluorides and oxyfluorides. In these compounds the electrons, from 5p orbitals are excited to 5d orbitals. The predicted shapes of xenon fluorides are linear, square planar and distorted octahedron. The shapes of xeon oxyfluorides can be prodicted by VSEPR theory.

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.
