The Structure of XeF4
XeF4, or xenon tetrafluoride, is a chemical compound that consists of one xenon atom bonded to four fluorine atoms. It is an interesting compound because it adopts a square planar molecular geometry, which is quite different from the usual octahedral or tetrahedral geometries seen in other compounds.
Molecular Geometry
XeF4 exhibits a square planar molecular geometry, which means that the xenon atom is located at the center of a square, with the four fluorine atoms positioned at the corners. This geometry arises due to the presence of lone pairs on the xenon atom. The lone pairs repel the bonding pairs, causing them to spread out as far as possible, resulting in a square planar arrangement.
Hybridization
The square planar geometry of XeF4 can be explained by the concept of hybridization. In XeF4, the xenon atom undergoes sp3d2 hybridization, which means that it combines one s, three p, and two d orbitals to form six equivalent hybrid orbitals. These hybrid orbitals are then used to form bonds with the four fluorine atoms.
Bonding
In XeF4, each fluorine atom forms a single bond with the xenon atom, resulting in four Xe-F bonds. These bonds are covalent in nature, with the xenon atom sharing its valence electrons with the fluorine atoms. The electron configuration of xenon is [Kr]5s24d105p6, and it can expand its valence shell by using its d orbitals. This allows xenon to accommodate the four fluorine atoms around it.
Lone Pairs
In addition to the four Xe-F bonds, the xenon atom in XeF4 also possesses two lone pairs of electrons. These lone pairs occupy two of the six hybrid orbitals, and they are responsible for the square planar geometry of the molecule. The presence of lone pairs causes repulsion between them and the bonding pairs, resulting in the square planar arrangement.
Conclusion
XeF4 is a compound with a square planar molecular geometry, where the xenon atom is bonded to four fluorine atoms. This geometry is due to the repulsion between the lone pairs and the bonding pairs, resulting in a square planar arrangement. The xenon atom undergoes sp3d2 hybridization to form six equivalent hybrid orbitals, which are used to form bonds with the fluorine atoms. The resulting molecule has four Xe-F bonds and two lone pairs of electrons.

Discuss the structure of XeF4?
Structure of XeF4
Xenon tetrafluoride (XeF4) is an inorganic compound composed of xenon and fluorine. It is a yellow crystalline solid that is stable at room temperature and pressure. XeF4 belongs to the space group D4h and has a distorted square planar molecular geometry. Let's discuss its structure in detail.
Electronic Configuration of Xenon (Xe)
Xenon is a noble gas with the atomic number 54. Its electron configuration is as follows:
1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6
Bonding in XeF4
XeF4 is formed through the combination of one xenon atom and four fluorine atoms. The xenon atom has eight valence electrons, while each fluorine atom contributes one electron, resulting in a total of twelve electrons surrounding the xenon atom.
Hybridization in XeF4
To accommodate the twelve valence electrons around the central xenon atom, hybridization occurs. The xenon atom undergoes sp3d2 hybridization, which means that it forms six hybrid orbitals by mixing one 5s, three 5p, and two 5d orbitals. These hybrid orbitals are oriented in an octahedral arrangement.
Geometry of XeF4
Due to the presence of six electron pairs (four bonding pairs and two lone pairs) around the central xenon atom, the molecular geometry of XeF4 is distorted square planar. The four fluorine atoms are arranged in a square plane, while the two lone pairs occupy the axial positions above and below the plane.
Bond Length and Bond Angle
The bond length between xenon and fluorine in XeF4 is approximately 1.95 Å. The bond angles within the square plane formed by the fluorine atoms are around 90 degrees, while the angles between the axial lone pairs and the fluorine atoms are approximately 180 degrees.
Intermolecular Forces
XeF4 exhibits weak intermolecular forces due to its molecular structure. The molecules are held together by van der Waals forces, which result from the temporary dipole moments induced by the movement of electrons.
Conclusion
In summary, XeF4 has a distorted square planar molecular geometry due to the presence of six electron pairs around the central xenon atom. It undergoes sp3d2 hybridization, forming six hybrid orbitals. The bond length between xenon and fluorine is approximately 1.95 Å, and the bond angles within the square plane and between the axial lone pairs and fluorine atoms are around 90 and 180 degrees, respectively. XeF4 exhibits weak intermolecular forces due to van der Waals interactions.
