Xenon tetroxide is a chemical compound of xenon and oxygen with molecular formula XeO 4, remarkable for being a relatively stable compound of a noble gas.It is a yellow crystalline solid that is stable below −35.9 °C; above that temperature it is very prone to exploding and decomposing into elemental xenon and oxygen (O 2).
The original synthesis of xenon tetrafluoride occurred through direct 1:5-molar-ratio combination of the elements in a nickel vessel at 400 °C. [9]The nickel does not catalyze the reaction, [citation needed] but rather protects the container surfaces against fluoride corrosion.
When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also
Xenon oxytetrafluoride (Xe O F 4) is an inorganic chemical compound.It is an unstable colorless liquid [2] [3] with a melting point of −46.2 °C (−51.2 °F; 227.0 K) [4] that can be synthesized by partial hydrolysis of XeF
XeO 2 is a yellow-orange solid. [4] It is an unstable compound, with a half-life of about two minutes, disproportionating into XeO 3 and xenon gas. Its structure and identity was confirmed by cooling it to −150 °C so that Raman spectroscopy could be performed before it decomposed.

An example of a polar surface is the rocksalt (111) surface. [2] In general, a polar surface is less stable than a nonpolar surface because a dipole moment increases the surface Gibbs energy. Also, oxygen polar surfaces are more stable than metal polar surfaces because oxygen ions are more polarizable, which lowers the surface energy. [9]
