The organization of the text is based on essays and topics of current interest. The lab manual contains a comprehensive treatment of laboratory te...show morechniques.
NEW! A new focus on Green Chemistry has been added to introduce environmentally responsible laboratory methods. New material includes experiments, descriptions of "green" methods, and the essay, Green Chemistry. The new experiments include an extraction using supercritical carbon dioxide, an isolation experiment that utilizes solid phase extraction tubes, an experiment that can be conducted in a conventional microwave oven, and an alternative to the standard chromic acid oxidation. Other experiments have been modified to reduce their use of hazardous solvents.
For discovery-based learning needs, open-ended experiments are provided to allow students to "write" their own experimental procedures and make their own discoveries.
Infrared, proton NMR, and 13C NMR spectroscopy is incorporated into many experiments. Some experiments also have an option to use gas chromatography-mass spectrometry.
Molecular modeling experiments give students an opportunity to experience the power of molecular modeling software.
The textbook contains a variety of experiments using microscale glassware and equipment.
Essays and examples on contemporary topics spark student interest and engage them in the learning process.
Experiments are well-written, comprehensive, class-tested, and proven over time.
"Caution" boxes emphasize careful handling of chemicals and the importance of safety in the laboratory.
Clear and accurate diagrams of laboratory set-ups increase students' confidence in setting up a lab.
End-of-chapter problems test students' mastery of the material.
NEW! The Techniques chapters are extensively reorganized. Laboratory Safety is now its own technique chapter and a new technique chapter, How to Find Data for Compounds: Handbooks and Catalogs, is included. New problems have been added to the chapters on infrared and NMR spectroscopy and many 60 MHz NMR spectra have been replaced by more modern 300 MHz spectra.
NEW! Substantial revisions were made to the Petroleum and Fossil Fuels essay.
NEW! The more than ten new experiments include: Experiment 11 Isolation of Caffeine from Tea (with a new procedure that utilizes solid phase extraction tubes); Experiment 13 Isolation of Eugenol from Cloves (with a new procedure based on a supercritical carbon dioxide extraction); Experiment 35 An Oxidation-Reduction Scheme: Borneol, Camphor, Isoborneol (with a new, solventless procedure); Experiment 44 The Wittig Reaction: Preparation of 1,4-Diphenyl-1,3-butadiene (with a new, solventless procedure); and Experiment 63 Synthesis of Substituted Chalcones: A Guided Inquiry Experience.
NEW! The tables of unknowns for the qualitative analysis experiment (Experiment 54 Identification of Unknowns) and Appendix 1 have been greatly expanded.
NEW! Chiral gas chromatography has been included in the analysis of the products of the resolution of alpha-phenylethylamine (Experiment 40) and the chiral reduction of ethyl acetoacetate (Experiment 33).
NEW! For the qualitative analysis experiment (Experiment 54) a new, optional test can be used in place of the traditional chromic acid test allowing for a safer experiment that does not require contact with hazardous chromium compounds.
NEW! Many experiments have been modified to improve their reliability and safety.
Green chemistry, an increasingly important topic, is introduced through an easy and experimentation.
