XeF2 has a liner shape. Why ?

Expert Answer:
Xenon has three lone pairs as well as three bonding pairs around it in XeF2. Five electron pairs -----> sp3d hybridization. The lone pairs repel each other more strongly than bonding pairs.
Therefore, it takes the three equatorial positions of the bipyramidal structure of sp3d hybridization, where they can be separated by 120 degrees.
If any one were to occupy the axial position, there would be a 90-degree LP-LP interaction.
Hence, the two bonding pairs occupy the axial positions, and the molecule is linear.
