Get ready to learn and work in the organic chemistry lab with Williamson/Masters' MACROSCALE AND MICROSCALE ORGANIC EXPERIMENTS, 8th Edition. Within each chapter, you’ll find new graphic color images and concise text to engage you more deeply in the lab experience. Features like “Lab Logics!” and “Mind Your Mechanisms” will require you to think as you complete the steps necessary in each experiment. The spiral-bound text will make it easier to read along in the textbook while you’re in lab. Using the manual's mix of macroscale and microscale experiments, you'll gain the knowledge and confidence you need to perform a wide variety of lab techniques and experiments, and you will also gain experience working with conventionally-sized glassware.

  • Kenneth L. Williamson

    Ken Williamson is retired from Mt. Holyoke College where he taught the organic chemistry laboratory course. He is an established authority on microscale techniques and regularly holds workshops and travels to campuses in the U.S., Canada, and Europe to demonstrate the use of microscale.

  • Katherine M. Masters

    A PhD from Pennsylvania State University, Katherine Masters is director of the organic chemistry laboratory courses at Penn State.

  • “Lab Logics!” callouts feature questions or important points for students to ponder and answer. These callouts are meant to require students to think about certain steps of an experiment and to dig deep into the “why” behind the steps.

  • “Before-During-After” models help students visualize and understand what is happening in an experiment.

  • “Mind Your Mechanism” callouts test students' understanding of a reaction’s mechanism, which can help student understanding of the functions of reagents and reaction conditions.

  • Two new chapters appear in this edition. The new “Getting Started” chapter includes a broad overview of organic chemistry, a set of learning goals and learning outcomes of the organic chemistry lab course, a check-in day discussion, and more! The new “Testing the Techniques” chapter requires students to design and carry out two experiments that require the separation of compounds using the separation/purification techniques learned in earlier chapters.

  • Printed as a spiral-bound book that is easier to use in the lab and is best for notetaking.

  • Dense text has been made concise to improve readability.

  • Chapter content has been reworked for better flow of thought and comprehension.

  • New graphics are used to summarize and highlight main points of selected topics; they are easier to read and intended to increase student engagement.

  • This edition features current models of instrumentation and methods of researching chemical literature.

Cengage provides a range of supplements that are updated in coordination with the main title selection. For more information about these supplements, contact your Learning Consultant.
