The valence bond formula of XeF2 with free electron pairs.

Xenon difluoride is a chemical compound with the formula XeF2. This noble gas compound can be used as a good fluorinating agent. Xenon diflouride is the most stable compound of all xenon compounds.

The compound shows a trigonal bipyramidal pseudostructure or a linear real structure in VSEPR theorie.

Xenon diflouride is solid in state of matter. It is achromatic and in christal form. Under high pressure and temperature, the compound can be produced from xenon and flourine directly.

Xe + F_2 \to XeF_2

Xenon diflouride is used in organic syntheses as flourinating agent.

Xenon diflouride can be destroyed by heating. It then results in the pure substances flourine and xenon. This reactions happens explosively, even thought that the enthalpy of reaction is negative ( \Delta_\mathrm{f}H^o = -163 \frac{kJ}{mol}). That is because the reaction changes the state of matter from solid to gas. The gas needs more space in room.
