Jones and Bartlett: Sudbury, MA. Organic Chem I workbook, $15; Organic Chem II workbook,
$19.95; IBM I, v. 2.0, Organic Chem, $495; IBM II, v. 2.0, $595.
The Chem TV: Organic
Chemistry series is a two-CD-ROM set, with the material divided loosely along the
lines of material typically covered in the two semesters of
introductory organic chemistry. Each CD-ROM contains
sections on Structure, Reactions, and Special Topics;
Organic Chemistry II also has treatment of Biochemical Structures and
a selection of Self-Tests.
There is an excellent initial interface, which shows
the user how to manipulate the software, offers suggestions
for classroom projection, order of coverage, computer
set-ups, and the like, and includes an animated
demonstration. There is also a Master Document, which contains titles
and brief descriptions of the animations included.
The sections on Structure are mainly
Hypercard-like slide shows with some animation. Most movies actually
consist of a number of short animated sequences, and the
user must keep hitting the play button to get through the
entire sequence. Although this may be useful for dividing
information into discrete segments, it makes the
experience somewhat disjointed. For the most part, the movies in
the Structure sections appear to be less instructive than
having the students work with a model set. There are
exceptions, however, as the section on butane does an
excellent job of correlating conformations with potential energy.
The section on Carboxylic Acids/Derivatives does a very good
job of showing the difference between addition/elimination
reactions to these compounds and the addition of
nucleophiles to aldehydes and ketones.
The sections on Reactions are more useful. In
general, the movies in these sections show the progress of a
reaction by first indicating the movement of and bonding
between nuclei, followed by a second run-through using
the curved-arrow notation. Some of the movies are
excellent: the section on Electrophilic Aromatic Substitution does
a superb job of showing how substituents can activate or
deactivate the aromatic ring; the treatment of Catalytic
Hydrogenation of Alkenes does a very good job of showing
the syn addition of hydrogen and discussing the concept
of prochiral faces; and the sections on alkyllithium
reagents and lithium dialkylcuprates contained in the Reactions
of Organometallic Reagents do an excellent job of showing
the mechanisms of how those reagents react. Other sections
of note include Bromination of Alkenes and the
DielsAlder Reaction. Unfortunately, the treatments of
SN1, SN2, E1 and E2 are somewhat uneven.
The sections on Biochemical Structures are very
detailed and much of it may be beyond the level of the
introductory organic chemistry course. The material is very
instructive, however, and much of it may be incorporated
in the core of the course. For instance, the illustration of
the cyclization of saccharides, and the equilibrium between
alpha and beta anomers and the acyclic form is
well-designed and would be a nice addition to any discussion of
acetal/ketal chemistry. The Special Topics are similarly
interesting, and correspond to many of the topics at the end of
the book that we always hope to get to, but usually don't
manage to cover.
There are a few minor problems that make
Chem TV: Organic Chemistry somewhat more difficult to use than
is necessary. The first is that although the Master
Document gives a listing of the movies along with a brief
description of their contents, the movies are not accessible from
this menu. Instead, the user must open another file and find
the desired movie from a list containing cryptic names, such
as a04funct.exe. Also, the movies make extensive use of
space-filling models, which sometimes make it difficult to
follow the reaction. All in all, Chem TV: Organic
Chemistry and Organic Chemistry II can be considered to be useful
supplements to lecture material, especially for reaction pathways.
