No doubt, many students equate enrolling in
organic chemistry to booking passage on the Titanic. After
securing first-class ticketsour students can spend $250 on
text, solutions manual/study guide, lab book, and model kit (not
to mention an optional book on spectroscopy)they
embark upon the rough waters of molecular structure,
reaction mechanism, and spectroscopy with frequent queasy
surges of chirality, reactions, synthesis, etc.
The prospect of owning one's own personal life raft
is tempting. Insurance against the elements. Suzanne
Theresa Mabrouk has "custom published"
The Organic Chemistry Survival Manual to assist organic students on their
voyage, but upon reviewing the manual I'm skeptical of
its value.
This 115-page paperback begins with some
general study hints and ends with a section on synthesis. In
between, in less-than-one to a-few-page segments, it
presents information on drawing organic structures, isomers,
functional group classifications, nomenclature, physical
properties, resonance, and mechanisms. The principal
difficulty that I have with the text manifests itself early, and
often. The "12 helpful study hints" section opening the book
includes a full page that maps over 20 reactions of
carboxylic acids. A student reading this first section on opening
day could not place this map or several other structures or
technical words in the section into any context. Similarly, in
the following section on electronic configurations, a
full-page chart, without explanation, states the hybridization of
oxygen in methanol is sp3, in furan is
sp2. Students are unlikely to appreciate the concept of aromaticity at this point in the course. Later, discussing Fischer and Haworth
projections, the text references stereocenters,
R, S, D, L, and sugar structures before any of these topics has been presented. This approach is typical throughout the book, and
consequently, it is difficult to understand how a student could use
the manual. Each section is more a summary of the topic,
that could be used to study for a final exam, than a
progressive guide to be used as the course unfolds.
The book is not entirely free of
typographical/omission errors, most of which could easily be corrected by
alerting the students in advance. There is some presentation of
material with which I have some quibble, however. For
example, the section on electrophilic addition to dienes,
states "Following the addition of H+ to the [1,3-buta]diene,
two resonance forms are generated. The chloride ion adds
to both carbocations ." Similarly, in electrophilic
aromatic substitution, the text presents the arenium
contributors without reference to a resonance hybrid.
The manual frequently summarizes a topic by enumeration. A problem develops when a set of rules, for instance, is not accompanied by sufficient examples to
explain the rules. The section on resonance structures provides
nine rules and a couple of sample problems, but doesn't
connect the two very well. On balance, however, most sections
have adequate examples. The text contains few sample
problems, and no problems for students to work on their own.
Mabrouk's goal is one shared by most of us who
teach organic chemistry. How can we best encourage and
assist our students? She has ambitiously prepared a
survival manual tailored to her course, her teaching style, and
her students. Unfortunately, the guide is not likely to travel
well to other courses, other teachers, or other students.
