The book is directed at the one-semester organic
course taught at most colleges and universities. Students in
these classes are typically enrolled in agricultural,
environmental, forestry, and health-related programs and need a basic
level of understanding of organic chemistry principles for
their chosen occupations (whether they realize it or not!).
Oftentimes this class is taught without a lab and it represents
the first and only time that organic principles are presented
to these students.
The text is divided into functional group-based
chapters, as are most texts. However, Johnson believes
in providing information on a "just-in-time" basis. For example, Chapter
1 (Carbon Compounds: Bonding and Structure)
presents sp3 carbon hydridization and reserves
complete discussion of sp2 and sp hybridization for Chapters 6 and 7. At this
point the student has been exposed to the conformational
aspects of cyclohexanes (Chapter 2), enantiomers (briefly, Chapter
3), and carbohydrates (Chapter 4). This format can be
difficult to get used to. Discussing molecular shape in Chapter 1
without full knowledge of the hybridization and bond angles of
double and triple bonds seems incomplete. However, on the plus
side of such an approach, leaving out a lot of the "stuff I have
to memorize" allows more room for the presentation of
"real-life" materials such as carbohydrates, a subject of
tremendous importance to the students enrolled in one-semester
organic classes. Too often this material, along with nucleic acids,
fats, and proteins, is given only cursory mention, if any at
all. This is unfortunate. The chemistry of these compounds
is precisely what should be emphasized to this audience!
The interweaving of biochemistry and
real-world examples into the text is good. Fifty-three vignettes entitled
"Chemistry at Work" provide commercial and biochemical examples
of organic chemistry. Johnson has also attempted to help
the student formulate a plan of attack when answering
questions, with sections entitled "How to Solve a Problem". These
sections walk through the problem-solving approach in much the
same way as one does when working examples in lecture.
The "Conceptual Problems" at the end of most chapters are
excellent, giving the student some pretty substantial and
timely things to ponder. I also appreciated the inside front
cover, which displays not only the important functional groups,
but also the relationships between them.
Like most textbook publishers these days, Jones and
Bartlett provides a teaching "package" that includes an
instructor's toolkit (CDROM). They also maintain an
impressive Web site (Organic Online) for users of the text, with icons
indicating where appropriate material can be found within
the site. The site contains Chime molecules, mechanism
movies, quizzes, and information on chemistry-related
careers. I think these sites should enhance the student's
understanding and appreciation of the subject matter. The solutions
manual (also prepared by Johnson) adequately summarizes the
material discussed in the text.
There are relatively few mistakes in the book,
considering that it is a first edition. The early discussions of
enantiomers could be improved, as could the section on carbohydrates
and polysaccharides. Also, there is no mention of aldol
reactions. Finally, in my opinion, there is a bit too much emphasis
on retrosynthetic analysis--something many students
have trouble with. However, even when considering
the above issues, if you can buy into the "just-in-time"
philosophy, I believe this is a very good one-semester organic text,
comparable to the others on the market. The response
from my fall 1999 class was quite positive, the biggest
complaint being the author's tendency to refer to later chapters
for more complete discussion of particular concepts (the
major drawback of the just-in-time philosophy).
