The Classroom Performance System’s

Written by Robert C. Atkins (James Madison University)
and Francis A. Carey, the Solutions Manual provides
step-by-step solutions to guide students through the
reasoning behind solving each problem in the text. There
is also a self-test at the end of each chapter designed to
assess the student’s mastery of the material.

(CPS) eInstruction brings interactivity
into the classroom or lecture hall. It is
a wireless response system that gives
the instructor and students immediate
feedback from the entire class. The
wireless response pads are essentially remotes that are
easy to use and engage students. CPS allows instructors

to motivate student preparation, promote interactivity
and active learning, and receive immediate feedback to
assess student understanding. Questions covering the
content of the Organic Chemistry text and formatted
in the CPS eInstruction software are available on the
Organic Chemistry ARIS™ site.

About the Cover
Chemists are increasingly concerned with preparing compounds designed to have particular properties. The compound featured on the cover is the
creation of Dr. Dirk Guldi of the University of
Erlangen (Germany) and Dr. Maurizio Prato of the
University of Trieste (Italy).
The cylindrical object is a form of carbon
known as a nanotube.* About 1 percent of the carbons of this nanotube are linked to molecules of
the organometallic “sandwich” compound ferrocene.† On irradiation with visible light, ferrocene
transfers an electron to the nanotube, generating a
charge-separated species. Thus, nanotubes that bear
appropriate attached groups hold promise as materials suitable for devices, such as solar cells, that
are capable of converting sunlight to electricity.

About the Author
Francis A. Carey, a native of Philadelphia, was educated at Drexel University (B.S. in
chemistry, 1959) and Penn State (Ph.D., 1963). Following postdoctoral work at Harvard
and military service, he served on the faculty of the University of Virginia from 1966
until retiring as Professor Emeritus in 2000.
In addition to this text, Professor Carey is coauthor (with Robert C. Atkins) of
Organic Chemistry: A Brief Course and (with Richard J. Sundberg) of Advanced Organic
Chemistry, a two-volume treatment designed for graduate students and advanced undergraduates.
Frank and his wife Jill, who is a teacher/director of a preschool and a church organist,
are the parents of Andy, Bob, and Bill and the grandparents of Riyad and Ava.
