Written for the laboratory that accompanies the sophomore/junior level courses in Organic Chemistry, Zubrick provides students with a valuable guide to the basic techniques of the Organic Chemistry lab. The Organic Chem Lab Survival Manual will help students understand and practice good lab safety. It will also help students become familiar with basic instrumentation, techniques and apparatus and help them master the latest techniques such as interpretation of infrared spectroscopy. The Organic Chem Lab Survival Manual is mostly macroscale in its orientation.
