Select incorrect statement for xenon fluorides :

When xenon fluoride reacts with SiO₂ to form XeOF₄ which finally forms XeO₃ (an explosive substance in dry state).

$\begin{array}{ccc}2{\mathrm{XeF}}_6+{\mathrm{SiO}}_2& \to & 2{\mathrm{XeOF}}_4+{\mathrm{SiF}}_4\\ 2{\mathrm{XeOF}}_4+{\mathrm{SiO}}_2& \to & 2{\mathrm{XeO}}_2{\mathrm{F}}_2+{\mathrm{SiF}}_4\\ 2{\mathrm{XeO}}_2{\mathrm{F}}_2+{\mathrm{SiO}}_2& \to & 2{\mathrm{XeO}}_3+{\mathrm{SiF}}_4\end{array}$

XeF₆ undergoes disproportionation in the presence of NaOH.

${\mathrm{XeF}}_6+\mathrm{NaOH}\stackrel{\mathrm{RI}}{\to }{\mathrm{XeO}}_6^{4-}+\mathrm{Xe}+{\mathrm{O}}_2+{\mathrm{F}}^{-}\left(\mathrm{aq}\right)$
