D~aeramsare used freauentlv considerably. This is a very readable text. I t proceeds very logically and does not attempt to averwhelm the reader. T h e treatment relies upon mathematics as little as possible. It appears tn this reviewer that this is a "student's" textbook and one that he or she will enjoy using. At the same time, all the topics necessary for a course of this type arecovered fully and adequately. Those looking for a text to use in a first year course for those students entering the health science field should consider this text. Students will like it. Rev. Addison Yehl

Higher Grade Chemlstry l o i n M. Duncan, Heinemann Educational Books, Ltd., London, 1978. iii + 185 pp. Fig. and tables. 23.2 X 15.5 cm. $6.25. A numher of important points about this paperback book can he made from the Note to Teachers. While the hook is designed for pupils in the Scottish "H"Grade, and perhaps other p o s t - " 0 level courses, its greatest use in this country will be in high school and possibly terminal beginning chemistry courses a t the college level. T h e oddities of language in this book printed in Great Britain will offer no problem, except perhaps a reference to the ocean liner Queen Elizabeth as QE2. T h e abbreviation p.d. far potential difference is not adequately defined. Theohjectives asstated by theauthorsare "to present patterns rather than unrelated facts" and "to clarify the difficult and key concepts." In a style much like texts written for self-paced instruction, the author does a rather good job of meeting his ohjeetives. T h e text is divided into 13units, with one unit on atoms and the mole, one unit on chemical bonding, three units on energy, equilibrium, and electrochemistry, one unit on kinetics, two units on periodicity, four units on organic chemistry, and one unit on nuclear chemistry. The book has noappendix, no periodic chart, and no table of atomic numbers and atomic weights. T h e index is sufficient.

knowledge assumed. In most cases the assumed previous knowledge is reasonable, but there are a few exceptions. For example, the first unit on atoms and the mole assumes familiarity with malarity. A number of selftests are found in each unit with reasonable, but searchine auestions. About half the on why responses are right or wrong. Only the simplest of mathematics is required. Simple stoichiometry, Hess's Law problems, electrochemical cell potentials, and bond energies comprise almost all the numerical problems in the text. Little to no attention is paid to significant figures. All numerical examples and answers to pmblems were found to be accurate. However, answers to some conceptual questions are questionable, and a m e t i m e s misleading. I t can he argued, though, that the answersare suitable for students for whom the book is written. T h e textual material also contains some misleading statements, mast of which could be corrected by minor wording changes. A more serious problem is the author's asking students tc, calculate the potential of the electrochemical cell, K/K+(.,,lMgZ+(.,~lMg. Only one chemical equation was detected to be in error, but it should not hinder students. In the introductory remarks, the author points out that some unusual approaches to the subject matter are presented. He further states that some might find his method of naming organic compounds unacceptable. Compounds such as 2-propanol and 2methyl-2-butene are named propan-2-01 and 2-methylbut-2-ene. T h e book is attractive inside and out. The cover has the feel of a rough-textured vinyl wallpaper and should prove very durable. The experience of the author with students for whom this book is written isdemonstrated in the short, simple, easy-to-understand sentences and the large number of very good diagrsms. T h e author's approach to the subject matter and his technique of reminding students of key concepts frequently will help students understand and retain the material. Instructors of chemistry may find more value in this book than students for two reasons. One is theauthor's practical and simple methods of presenting the subject matter to students at this level. T h e more important reason is that the large numher of fine graphs and diagrams will give chemistry teachers pointers on how to better construct their own graphs and diagrams to illustrate and to communicate chemical principles in a simple manner.

This textbook is very similar to a number of other texts written for the year course in

organic chemistry. It is organized around the traditional functional group approach that, in the words of the authors, "provides a framework for learning." The first two chapters include a review of atoms; molecules, orbitals, and honding. In Chapter 3, nomenclature of the major classes of organic compounds is introduced and is followed by alkanes. Chapter 4 is a discussion on sterenchemistry. Alkyl halides and substitution and elimination reactions are covered in Chapter 5. Mechanisms and energy profiles are first presented in connection with the discussion of S ..N .~8 .~. 2. E. l and E2 tvoe reactions.

Beginning with Chapter 9 there is a series of chapters based on functionality and includes unsaturated compounds, ammaticity, aldehydes and ketones, carboxylic acids, acid derivatives of carboxylic acids, endates and carbanions, amines and polycyclic and heterocyclic aromatics. Chapters 17, 18, and 19 are also topical covering carbohydrates, amino acids and proteins, and lipids and related natural materials.
