Teaching Structure–Property Relationships: Investigating Molecular Structure and Boiling Point  Peter M. Murphy
The boiling points for 392 organic compounds are tabulated by carbon chain length and functional group to facilitate a wide range of inquiry-based activities that correlate the effects of chemical structure on physical properties.

Semiempirical and DFT Investigations of the Dissociation of Alkyl Halides  Jack R. Waas
Enthalpy changes corresponding to the gas phase heats of dissociation of 12 organic halides were calculated using two semiempirical methods, the HartreeĀFock method, and two DFT methods. All five methods agreed generally with the expected empirically known trends in the dissociation of alkyl halides.

The Story of the Wagner-Meerwein Rearrangement  Ludmila Birladeanu
This paper tells the story of the long, arduous journey toward comprehending the mechanism of molecular rearrangements. This work involved the greatest chemists of the 19th and 20th centuries, among whom two names stand out: Georg Wagner, who showed what happens in these strange reshufflings of atoms, and Hans Meerwein, who showed how it happens. The resulting insight revolutionized the theory of organic chemistry.

On the boiling points of the alkyl halides  Correla, John
Most textbooks spend some time discussing the relationship between boiling point and molecular structure, however, their reasons behind this relationship differ. This variation among textbooks warrants further investigation and discussion in order to uncover which of the factors are the major contributors to the variation of boiling point.
