Despite having a closed-shell electronic configuration, noble gases can form compounds through the sharing of their boundary electrons. The compound Xe (F) 6 is a classic example of compounds involving noble gases. Using Xe (F) 6 answer the questions below:
(a) How can we explain the formation of Xe-F connections?
(b) There is still some controversy regarding the geometry of XeF6. According to the Theory of Repulsion of the Electronic Valve Layer Pairs (RPECV) the XeF6 presents 7 pairs of electrons in the valence layer which would lead to a pentagonal distortion bipyramid configuration. However, infrared and Raman spectroscopy data point to a perfect octahedral geometry. How can we differentiate the two geometries through these techniques?
