Abstract
In this Communication we describe the use of nondeuterated solvent NMR spectroscopy experiments in large enrollment organic chemistry teaching laboratories. We use deuterated solvent free NMR spectroscopic analysis of several base promoted alkyl halide substitution and elimination reactions, which are taught ubiquitously in undergraduate organic chemistry, to demonstrate its utility and reliability for large enrollment classes. When such NMR experiments are used to track reaction progress and mechanism, they are found to be extremely useful and reliable, keeping waste generated in the laboratories and the price of experiments low, all while eliminating the need for deuterated halogenated NMR solvents.
期刊介绍:
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
