Application of ChemDraw NMR Tool: Correlation of Program-Generated 13C Chemical Shifts and pKa Values of para-Substituted Benzoic Acids  Hongyi Wang
An application of ChemDraw NMR Tool was demonstrated by correlation of program-generated 13C NMR chemical shifts and pKa values of para-substituted benzoic acids. Experimental 13C NMR chemical shifts were analyzed in the same way for comparison. The project can be used as an assignment at the end of the first-year organic chemistry course to review topics or explore new techniques: Hammett equation, acid¬Ěbase equilibrium theory, electronic nature of functional groups, inductive and resonance effects, structure¬Ěreactivity relationship, NMR spectroscopy, literature search, database search, and ChemDraw software.

Using Hydrocarbon Acidities To Demonstrate Principles of Organic Structure and Bonding  Andrew P. Dicks
This article demonstrates the utility of hydrocarbon acidity as a teaching tool within the undergraduate classroom. Acidities of compounds containing only hydrogen and carbon vary by at least 50 orders of magnitude. Differences in acidities are rationalized by invoking principles of hybridization, resonance, induction, and aromaticity.

Acidities of oxoacids: Correlation with charge distribution  Meek, Terry L.
In an attempt to ascertain whether acidity can be correlated with some molecular parameter, the charge distribution within 24 oxoacid molecules and their conjugate base anions were examined by calculating the partial positive or negative charge on each atom.

Effect of amine structure on the relative acidity of conjugate acids  Griswold, Robert E.
the primary objectives of this experiment are to investigate the effect of structure of amines on the relative acidity of their conjugate acids and to study some of the factors affecting equilibrium constants.
