EBOOK - A Small Scale Approach to Organic Laboratory Techniques (Donald L. Pavia)
The purpose of this lab book is to teach students the techniques of organic chemistry. We desire to share our love of the organic chemistry lab and the joy it brings us with our students! In this edition, we have provided many new, up-to-date experi-ments that will demonstrate how organic chemistry is evolving. We have updated and improved many of the standard experiments from previous editions, and we have added some new ones.
For example, we have included some experiments in-volving dyes. For fun, we have added a project experiment that asks the students to formulate a paint and then use it in an art project. We think that you will be en-thusiastic about this new edition. Many of the new experiments will not be found in other laboratory manuals, but we have been careful to retain all of the standard reactions and techniques, such as the Friedel-Crafts reaction, aldol condensation, Grignard synthesis, and basic experiments designed to teach crystallization, chro-matography, and distillation.
