Structure of rare gas compounds

Modern valence bond theory is also applicable to the discussion of the molecular structure of rare gas compounds
.

According to the theory of mutual exclusion of electron pairs in the valence layer, the electron pair configuration of XeF ₂ is a triangular biconical shape, while the molecular configuration is linear, as shown in Figure 14-1(a); Xe adopts sp ³ d heterogeneity
.

The electron pair configuration of XeF ₄ is a regular octahedron, and the molecular configuration is a square, as shown in Figure 14-1(b); the atomic orbitals of Xe adopt sp ³ d ² unequal hybridization
.

In the XeF ₆ molecule, the number of pairs of electrons in the valence layer of Xe is 7, and the number of pairs of bonding electrons is 6, and there is 1 lone electron pair
.
