Answered: Draw the major products of the major | bartleby Easy Questions. If you are still unsure, ask a friend or . Often, the structure is described as having a stereochemically active but fluxional lone pair, which is generally accurate; however, VSEPR cannot be used to predict the region of space which the lone pair occupies. Point groups are used in Group Theory, the mathematical analysis of groups, to determine properties such as a molecule's molecular orbitals. Gas-phase electron diffraction (dating from 1968) showed that the structure was approximately, but not exactly, octahedral: the experimental diffractogram differed from the theoretical diffractogram calculated for a hypothetical octahedral molecule.1 The authors considered a wide range of possible geometrical distortions, and found that $C_\mathrm{2v}$ or $C_\mathrm{3v}$ structures were relatively consistent with the spectrum obtained, with the latter being the most probable configuration.2 These could be interpreted in terms of a stereochemically active lone pair: If we start with an undeformed octahedron we can characterize the deformation to the equilibrium structure in terms of the site of the repulsive lone pair [] Symmetry considerations would seem to dictate that the lone pair be centered on the corner, face, or edge in the equilibrium structure.
[Solved] What is hybridisation of XeF6 in solid state? This was occasionally presented as evidence for an undistorted structure, but the calculations did not take into account the possibility of a highly fluxional process, and later Bernstein and Pitzer showed that depending on the barrier height, dipole moments up to $\pu{0.6D}$ could be plausible.7 On top of that, the distorted conformers were not expected to have large dipole moments, as the dipole moment of the lone pair would oppose the net dipole moments of the $\ce{Xe-F}$ bonds. Why do compounds like SF6 and SF4 exist but SH6 and SH4 don't? From: Theoretical and Computational Chemistry, 2003. XeF6 Molecular Geometry contains one atom of xenon and six atoms of fluorine.

Prediction of stable radon fluoride molecules and geometry optimization using first-principles calculations. Together, these clearly show that even the second-order JahnTeller approach described earlier is incomplete, as it fails to explain other species valence isoelectronic with $\ce{XeF6}$.
