book reviews This book can be a valuable reference work for scientists actually involved in air pollution research. It will also serve well as a textbook for many courses in departments of meteorology, oceanography, and civil engineering. The chemical aspects of atmospheric science and air pollution are not presented in enough depth to make the book entirely satisfactory as the text for a course in air chemistry taught in a chemistry department. The cost ($10.951 generally will prevent the use of the book as one of the texts in an environmental chemistry course in combination with another text for the aquatic chemistry section of the course.

This hook, designed in presentation and context for those who have had a t least a one-year exposure to organic chemistry, treats in highly readable fashion the complex problem of aromaticity and its more

recent extensions (homoaromaticity, bicycloaromsticity, etc.). The volume begins with a brief historical discussion of the structure of benzene and the suhsequent stepwise solution of this problem as quantum mechanics, the Hiickel method, and the valence bond approach became available to the chemical community. Chapter 2 serves to compare and contrast the electronic constructs, physical properties, and chemical reactivity of cyclobutadiene, benzene, and cyclooctatetraene. The relevance of diamagnetic anisotropy, heat of combustion and hydrogenation data, electronic spectra, and fluxional properties are neatly interwoven in a systematic and attractive manner. Next is a discussion of the annulenes which is more extensive than any other segment of the book undoubtedly because of the author's personal involvement with this area of research. Chapter 4 reviews in a m a t exhaustive yet concise way the subject of monocyclic aromatic ions. The entire speetrum of charged stabilized species ranging from the commonplace eyclopentadienide anion to the elusive [24]annulene dianion is presented with frequent references to MO properties and chemical reactivity. This is followed by a presentation of 4n r electron monocyclic antiaromatie ions and the marked contrast with the stabilized systems is accentuated as a result. Suhsequently, the text gives attention to annulenones, fulvenes, and related structural types, heterocyclic systems, polycyclic molecules, homoammatic and hicycloaromatie entities, and the criteria for aromaticity.
Efforts t o generalize the presentation of aromaticity are not new, but this comprises the first effort to present the subject in textbook format. Whether the text will succeed in the classroom will depend critically upon the composition of the student body and to a significant extent on the professor-in-charge.' The hook is heavily descriptive and only a relatively few general references are provided a t the end of each chapter. Although this does allow for some follow up by the student, the ahsence of exhaustive references does have its disadvantages, particularly where the introduction of supplemental material may prove desirable. The text does not dwell a t all on such subjects as benzenoid aromatic substitution but rather is most concerned with denoting the features which distinguish stabilized from destahilized nonhenzenoid molecules and ions. The format is more in the nature of a review (and an excellent one) than a teaching manual, and i t ih as updated a treatment of the subject as can be found. One might argue, however, that the cost of the bwk is rather prohibitive given its emphasis and made of presentation. For those interested in the field, i t is a refreshing and desirable presentation of the subject. To the uninitiated student, this teat could serve as a n enlightening expose of the current status of aromaticity. Finally, to the instructor who utilizes the book for classroom instruction, it will mean that he will have to provide a significant amount of additional relevant subject matter as suits his taste.
