Chemistry Education without Borders
The March 2015 issue of the Journal of Chemical Education is now available online to subscribers. This issue features NMR spectroscopy; chemistry teaching from an international perspective; chemistry & history; learning to think and work like a chemist; introductory laboratory experiences & experiments; the chemistry of fingerprints.
Cover: NMR Spectroscopy
As described by T. Andrew Mobley in NMR Kinetics of the SN2 Reaction between BuBr and I–: An Introductory Organic Chemistry Laboratory Exercise, students investigate the second-order kinetics of the reaction between BuBr and NaI in acetone-d6 by monitoring the progress of the reaction using 1H NMR spectroscopy. This classical reaction is ideal for introducing organic students to kinetic studies, as the simple 1H spectra allow the students to “see” the reaction as it occurs. Additional articles in this issue on NMR spectroscopy laboratories are listed below.
Norbert J. Pienta, Editor-in-Chief, has taken another trip to India and makes some observations in Innocents Abroad, Part II: A Glimpse at Chemical Education in India.
