Chapters 18 in bath books have the same title, The Chemistry of Carbon Compounds. Similarity of content exists. The new, t,ellingly presented and better organized, shows that certain physical evidences such as nuclear magnetic resonance are effective in establishing molecolar stroctore. Some omissions or slights remain in t,he new. The concept of pH broached in old and new receives little attention. Although terminology in the new is ourrent, it devotes neither time nor spaces to syat,emntic nomenclature. Lewis acid base theory got and gets short shrift,. The terms "equivalents" and "normality" lack existence in either text. Randomnws, treated in the old, gets far better lreatment in the new and even becomes known as "entropy." Free energy change as a. criterion of spont,aneity for chemical reaction in a chemical system gets no ment,ion. Students, however, have been brought near the point where free energy is a short step away, Questions a t the ends of chapters are, by and large, good, thought provoking exercises, but more of them cast in x qusot,it,ative vein would have been valuable. The baok, wit,h the same lateral dimensions as t,he original CHEM Rudy, cont,ains 620 nnmbered pages sturdily bound in a soil resistant cover. Except for italics and bold t,ype which emphasize key words and principles, standard print occnpies about two-thirds of each page. The paper, not sl,srrkwhite is good quality. A second color augments many well-coneeived illnstrations. Illnstrations, figures, tables, and so on find locat,ion near related t,ext,ualmaterial. These locations are usually on the onpitded margins but occx.iianally encroach npon amx usually reserved for print. Eleven appeudices and au extensive index make references sore, and easy. With pmctieally nil typographical errors, the reading level appears to be easily within the grasp of nverwe high school students and certainly is easier to comprehend than the original. The first eighteen ehapt,ers with intended laboratory activities constitute xn excellent, first,-year course. They include t,he necessary concepts, principles, and knowledge for fnrther study. If t,he teacher has permit,tcd, st~tdent,swill ~understand how seient,ists work. The remaining five chapters while extending knowledge afford st,udents an opportunit:)i t,o apply coneopts m d principles already learned. I n conclusion, t,he originxtms of CHEM Study intended that. their text, "Chemistrv: An Exoerimental Sciewe," be one of several i,~&wnent,soscd in teaching chemist,ry. Three of the four aot,hors of this t,ext were major eontribut,ors to CHEM Study. Certainly they and the fourth aubho~ look upon "Chemistry: Experimental Foundations" as the original
authors viewed "Chemist,ry: An Experiment,al Science." Qui1.e obviolmly I commend this work to any teacher who teaches first-year chemistry to average and above average high school st~~denls.I t ranks with the very best. C H . \ ~ ~ LW.
