Mark, James B. C.; Bedell, T. Aaron; DeLuca, Ryan J.; Hone, Graham A. B.; Roizen, Jennifer L.; Cox, Charles T.; Sorensen, Erik J.; Du Bois, J. – Journal of Chemical Education, 2018
An advanced undergraduate organic chemistry laboratory experiment involving a rhodium-catalyzed intermolecular hydrocarbon C-H oxidation reaction is described. In the initial phase of this lab, students conduct a C-H amination reaction of ethylbenzene and isolate a benzylic amine product. In the second part of the lab, competition experiments are…

Berger, Michael; Goldfarb, Jillian L. – Journal of Chemical Education, 2017
Engaging undergraduates in the environmental consequences of fossil fuel usage primes them to consider their own anthropogenic impact, and the benefits and trade-offs of converting to renewable fuel strategies. This laboratory activity explores the potential contaminants (both inorganic and organic) present in the raw fuel and solid waste…

Nordholm, Sture; Back, Andreas; Backsay, George B. – Journal of Chemical Education, 2007
The commonly used Huckel model of electronic structure is employed to study the mechanisms of covalent bonding, a quantum effect related to electron dynamics. The model also explains the conjugation and aromaticity of planar hydrocarbon molecules completely.

Struyf, Jef – Journal of Chemical Education, 2011
The boiling point of a monofunctional organic compound is expressed as the sum of two parts: a contribution to the boiling point due to the R group and a contribution due to the functional group. The boiling point in absolute temperature of the corresponding RH hydrocarbon is chosen for the contribution to the boiling point of the R group and is a…

Barrows, Russell D. – Journal of Chemical Education, 2007
A one-way ANOVA experiment is performed to determine whether or not the three standardization methods are statistically different in determining the concentration of the three paraffin analytes. The laboratory exercise asks students to combine the three methods in a single analytical procedure of their own design to determine the concentration of…

Golombok, Michael – Journal of Chemical Education, 2004
The interactive methods of steam hydrocarbon reforming and cracking of the oil and chemical industries are scrutinized, with special focus on their resemblance and variations. The two methods are illustrations of equilibrium-controlled and kinetically-controlled processes, the analysis of which involves theories, which overlap and balance each…

D'Amelia, Ronald; Franks, Thomas; Nirode, William F. – Journal of Chemical Education, 2007
In first-year general chemistry undergraduate courses, thermodynamics and thermal properties such as melting points and changes in enthalpy ([Delta]H) and entropy ([Delta]S) of phase changes are frequently discussed. Typically, classical calorimetric methods of analysis are used to determine [Delta]H of reactions. Differential scanning calorimetry…

Rivera-Figueroa, A. M.; Ramazan, K. A.; Finlayson-Pitts, B. J. – Journal of Chemical Education, 2004
A quantitative and qualitative study of the interplay between absorption, fluorescence, and excitation spectra of pollutants called polycyclic aromatic hydrocarbons (PAHs) is conducted. The study of five PAH displays the correlation of the above-mentioned properties along with the associated molecular changes.
