This text for the two-semester introductory organic chemistry lab offers a series of clear and concise experiments that encourage accurate observation and deductive reasoning. A focus on biochemical and biomedical applications renders the narrative ideal for the mainstream organic chemistry laboratory. Emphasis is also placed on safety and the disposal of hazardous waste. Pre-lab exercises, marginal notes, clear line drawings, and questions help retain student interest and comprehension from lesson to lesson. The Ninth Edition includes "In This Experiment" objectives that clarify the goals of procedures. Optional, additional "For Further Investigation" features offer an in-depth exploration of the chemical principles presented.
