Helping Students Assess the Relative Importance of Different Intermolecular Interactions
Jasien, Paul G.
Journal of Chemical Education, v85 n9 p1222-1225 Sep 2008
A semi-quantitative model has been developed to estimate the relative effects of dispersion, dipole-dipole interactions, and H-bonding on the normal boiling points ("T[subscript b]") for a subset of simple organic systems. The model is based upon a statistical analysis using multiple linear regression on a series of straight-chain organic compounds. Although it is not predictive in terms of the absolute boiling points of these compounds, this model provides a framework that may be useful to instructors and students in understanding the relative boiling points of compounds. Application of this model may be useful in addressing student misconceptions related to the additivity of intermolecular interactions, which is often not emphasized sufficiently in texts. (Contains 3 tables and 5 notes.)
