Lafarge, David L.; Morge, Ludovic M.; Méheut, Martine M. – Journal of Chemical Education, 2014
Organic chemistry is often considered to be a difficult subject to teach and to learn, particularly as students prefer to resort to memorization alone rather than reasoning using models from chemical reactivity. Existing studies have led us to suggest principles for redefining the curriculum, ranging from its overall structure to the tasks given…

McRae, Christopher; Karuso, Peter; Liu, Fei – Journal of Chemical Education, 2012
The Web is now a standard tool for information access and dissemination in higher education. The prospect of Web-based, simulated learning platforms and technologies, however, remains underexplored. We have developed a Web-based tutorial program (ChemVoyage) for a third-year organic chemistry class on the topic of pericyclic reactions to…

Duis, Jennifer M. – Journal of Chemical Education, 2011
An exploratory study was conducted with 23 organic chemistry educators to discover what general chemistry concepts they typically review, the concepts they believe are fundamental to introductory organic chemistry, the topics students find most difficult in the subject, and the misconceptions they observe in undergraduate organic chemistry…

Martin, Christopher B.; Schmidt, Monica; Soniat, Michael – Journal of Chemical Education, 2011
A survey was conducted of four-year institutions that teach undergraduate organic chemistry laboratories in the United States. The data include results from over 130 schools, describes the current practices at these institutions, and discusses the statistical results such as the scale of the laboratories performed, the chemical techniques applied,…

Kimbrough, Doris Renate; Jensen, Anna Chick – Journal of Chemical Education, 2010
An introduction to the chemistry of the triazine compound, melamine, is presented as well as a brief discussion of the health impacts on humans and pets when melamine contaminates milk products and pet food. Melamine has repeatedly been in the news, and its topical nature provides an excellent springboard for applications of a variety of chemical…

Loyson, Peter – Journal of Chemical Education, 2010
This article describes the use of Latin-derived words and terms used in chemistry, and explores the meaning of these words, so as to lead to a better understanding of these words, so commonly used in the teaching of chemistry. As the article shows, there are many such words, and with some elementary knowledge, a greater meaning is given to these…

McGrath, Nicholas A.; Brichacek, Matthew; Njardarson, Jon T. – Journal of Chemical Education, 2010
A new free graphical teaching tool that highlights the beautiful organic architectures of the top selling pharmaceuticals is detailed on two posters. In addition to the multitude of teaching and data-mining opportunities these posters offer, they were also created to emphasize the central role organic chemists play in the development of new…

Shibley, Ivan A., Jr.; Amaral, Katie E.; Aurentz, David J.; McCaully, Ronald J. – Journal of Chemical Education, 2010
A variety of approaches to the concept of oxidation and reduction appear in organic textbooks. The method proposed here is different than most published approaches. The oxidation state is calculated by totaling the number of heterogeneous atoms, [pi]-bonds, and rings. A comparison of the oxidation states of reactant and product determine what type…

Alaimo, Peter J.; Langenhan, Joseph M.; Tanner, Martha J.; Ferrenberg, Scott M. – Journal of Chemical Education, 2010
We developed and implemented a yearlong safety program into our organic chemistry lab courses that aims to enhance student attitudes toward safety and to ensure students learn to recognize, demonstrate, and assess safe laboratory practices. This active, collaborative program involves the use of student "safety teams" and includes…

Murphy, Thomas J. – Journal of Chemical Education, 2009
There are significant contradictions in undergraduate organic chemistry textbooks as to the mechanism of nucleophilic substitution reactions at saturated secondary carbons. Some texts say that only the S[subscript N]2 mechanism operates, others say that solvolysis reactions go entirely by the S[subscript N]1 mechanism, while most texts say that…

Sierra, Manuel Gonzalez; Pellegrinet, Silvina C.; Colombo, Maria I.; Ruveda, Edmundo A. – Journal of Chemical Education, 2008
An exercise on structure elucidation for advanced undergraduate students is described. To determine the structure of an unknown product, students are required to use spectra together with an organic chemistry mechanism. This exercise exemplifies the procedure commonly used in research, thus helping students develop problem-solving skills. In…

Clausen, Thomas P.; Green, Thomas K.; Steiner, Benjamin – Journal of Chemical Education, 2008
In teaching organic chemistry laboratory at this university, we eliminated the use of "canned" experiments from textbooks. Instead, we present students with literature studies that form the basis of developing new unpublished experiments to answer specific questions. In this research approach, students are better exposed to the chemical…

Green, Brian; Bentley, Michael D.; Chung, Bong Y.; Lynch, Nicholas G.; Jensen, Bruce L. – Journal of Chemical Education, 2007
The triterpenes are a diverse class of widely distributed natural products derived from squalene. Various cyclization and subsequent rearrangement reactions produce many complex structural types. These compounds frequently display a wide divergence of biological properties. For example the pentacyclic triterpene, betulin, is isolated from white…

Qvit, Nir; Barda, Yaniv; Gilon, Chaim; Shalev, Deborah E. – Journal of Chemical Education, 2007
This laboratory experiment provides a unique opportunity for students to synthesize three analogues of aspartame, a commonly used artificial sweetener. The students are introduced to the powerful and useful method of parallel synthesis while synthesizing three dipeptides in parallel using solid-phase peptide synthesis (SPPS) and simultaneous…

Greco, George E. – Journal of Chemical Education, 2007
An experiment for the upper-level undergraduate laboratory is described in which students synthesize a ruthenium olefin metathesis catalyst, then use the catalyst to carry out the ring-closing metathesis of diethyl diallylmalonate. The olefin metathesis reaction was the subject of the 2005 Nobel Prize in chemistry. The catalyst chosen for this…
