Predicting the Stability of Hypervalent Molecules

Journal of Chemical Education, 2007
In this exercise, students use concepts in thermochemistry such as bond energy, ionization potentials, and electron affinities to predict the relative stability of two hypervalent molecules (PF5 and PH5) relative to their respective non-hypervalent counterparts.

Chemical Bonding in Hypervalent Molecules:  Is the Octet Rule Relevant?

Inorganic Chemistry, 2002
The bonding in a large number of hypervalent molecules of P, As, S, Se, Te, Cl, and Br with the ligands F, Cl, O, CH(3), and CH(2) has been studied using the topological analysis of the electron localization function ELF. This function partitions the electron density of a molecule into core and valence basins and further classifies valence basins ...
