nificant pedagogical stumbling block— the rigorous teaching of organic chemistry, without inducing repugnance or rancor, to students for whom this will be a terminal chemistry course. The result is a volume which reads easily and yet preserves many of the organic chemist's cherished didactic approaches. The book was not intended to compete with the 2.0 to 2.5 kg tomes of modern basic organic chemistry. Reactions are arranged operationally rather than according to functional groups. The introduction to bonding and molecular orbitals is clear and conventional. Following these introductory chapters, organic reactions are examined with pleasing attention to mechanistic considerations. It is refreshing to see the traditional ''alkanes, alkenes, alkynes" approach has been abandoned in favor of reactions calculated to better evoke the interest of the student. The hydrocarbons of Chapter 3 serve only as a vehicle to examine nomenclature, to which subject the authors give proper stress. The discussion of acidity is especially straightforward and clear, as is the section on electrophilie aromatic substitution. The text is cleanly printed and has
been carefully edited. However, some three-dimensional drawings inaccurately portray the relationship of various molecular features and are misleading. The study problems of early chapters are too few in number and occasionally trivial but rise to an acme in Chapters 5-9. Beyond that point there are no problems, a fact which seriously diminishes the impact of the textual content. The index is spare and presents a handicap to the serious student. Conceptual errors are very few. However, one must be prepared to accept the occasional oversimplification and arbitrary statement of principle which necessarily are part of a text of this objective. The fundamental concept of resonance is introduced most casually, never clearly defined, and yet is employed with increasing frequency in later chapters. Another important defect arises as a result of the totally qualitative approach to the subject of energetics. There is no discussion of bond energies, of free energy and equilibrium, or of the range of energy in which organic reactions occur. As a consequence, when the student is confronted with the value of 38 kcal/mol for the resonance energy of benzene, he has neither

a prior framework to which he can numerically relate this important quantity nor a clear picture of its origin. Chapter 10 is an inadequate attempt to present "Organic Chemistry in a Nutshell" and might best have been deleted. Spectroscopy is appended, as if an afterthought, in the final chapter of the text. The central role of this topic in all aspects of organic chemistry should predicate in favor of its integration into the text or its presentation at a much earlier time. The authors' attention to the use of biologically or commercially interesting compounds to illustrate mundane synthetic methods is commendable. However, in the later chapters this propensity degenerates occasionally into a recitative of complex physiologically important molecules with little connective, narrative. The net impact could be to intimidate rather than enlighten the reader. The authors' penchant for phonetics will no doubt lead the student to state clearly that a given XU-klee-oh-file leads to ESS-EN-TOO substitution without RASS-em-ih-SAYshun, whether or not he understands the stereochemistry involved.
