Which of the following xenon-oxo compounds may not be obtained by hydrolysis of xenon fluorides ?

Solution :
\[\begin{align} & Xe{{F}_{6}}+{{H}_{2}}O\xrightarrow{\text{Partial}}XeO{{F}_{4}}+2HF \\ & Xe{{F}_{6}}+2{{H}_{2}}O\xrightarrow{\text{Partial}}Xe{{O}_{2}}{{F}_{2}}+4HF \\ & Xe{{F}_{6}}+3{{H}_{2}}O\xrightarrow{\text{Complete}}Xe{{O}_{3}}+6HF \\ \end{align}\]
