xenon-difluoride
Xenon difluoride is a colorless gas with a pungent odor. It is a powerful oxidizer and can react with many substances, including water, to produce heat and flames. Xenon difluoride is not very stable and can decompose explosively.
Xenon is a Noble Gas, but It Forms the XeF2 Compound, Why?
Xenon is a noble gas, meaning that it is inert and does not form compounds. However, it is possible to form the XeF2 compound by combining xenon atoms with fluorine atoms. This occurs because xenon has a higher electronegativity than fluorine, meaning that it attracts electrons more strongly. When the two atoms combine, the xenon atom transfers electrons to the fluorine atom, forming the XeF2 compound.
Bonding in XeF2
In XeF2, the atoms are held together by a covalent bond. In a covalent bond, two atoms share a pair of electrons. This creates a strong bond between the atoms.
Structure of Xenon Difluoride
Xenon difluoride is a molecule composed of one xenon atom and two fluorine atoms. The xenon atom is held together by a covalent bond to each of the two fluorine atoms. The fluorine atoms are held together by a polar covalent bond, in which the electron density is more concentrated on the oxygen atom than on the fluorine atom. This creates a partial negative charge on the fluorine atom and a partial positive charge on the oxygen atom. This charge difference creates a strong electrostatic force between the xenon atom and the fluorine atoms, which holds the molecule together.
Linear Synthesis of Xenon Difluoride
To synthesize xenon difluoride, xenon gas and fluorine gas are mixed together and then heated to a very high temperature. This causes the xenon and fluorine atoms to react and form xenon difluoride.
