Acknowledgments The preparation of a new edition is a continuous effort of many people. As in my work on other textbooks, I am thankful for the support, encouragement, and dedication of many people who put in hours of tireless effort to produce a high-quality book that provides an outstanding learning package. The editorial team at Pearson has done an exceptional job. I want to thank Adam Â�Jaworski, editor in chief, and executive editor, Jeanne Zalesky, who supported my vision of this fourth edition and the addition of the new Analyze the Problem feature; more Guides to Problem Solving; new Chemistry Links to Health, History, Â�Industry, and the Environment; new learning goals with section questions and problems; thumbnails in Chapter Review; matched problem sets; and an updated art program. I am in awe and much appreciate all the wonderful work of Jessica Â�Neumann, associate editor, who was like an angel encouraging me at each step while skillfully Â�coordinating Â�reviews, art, website materials, and all the things it takes to make a book come together. I appreciate the work of Beth Sweeten, project manager, and Andrea Stefanowicz of Â�PreMediaGlobal, who brilliantly coordinated all phases of the manuscript to the final pages of a beautiful book. Thanks to Mark Quirie and Vincent Dunlap, manuscript reviewers and Â�accuracy checkers, and Denise Rubens, copy editor, who precisely reviewed and edited the manuscript to make sure the words and problems were correct to help students learn chemistry. Their keen eyes and thoughtful comments were extremely helpful in the development of this text. I am especially proud of the art program in this text, which lends beauty and understanding to chemistry. I would like to thank Connie Long and Derek Bacchus, art director and book designer, whose creative ideas provided the outstanding Â�design for the cover and pages of the book. Eric Schrader, photo Â�researcher, was invaluable in researching and selecting vivid photos for the text so that students can see the beauty of chemistry. Thanks also to Bio-Rad Laboratories for their courtesy and use of KnowItAll Â�ChemWindows, drawing software that helped me produce chemical structures for the manuscript. The macro-to-micro illustrations designed by Production Solutions and Precision Graphics give students visual impressions of the atomic and molecular organization of everyday things and are a fantastic learning tool. I want to thank Denne Wesolowski for the hours of proofreading all the pages. I also appreciate all the hard work in the field put in by the marketing team and Erin Gardner, marketing manager. I am extremely grateful to an incredible group of peers for their careful assessment of all the new ideas for the text; for their suggested additions, corrections, changes, and deletions; and for providing an incredible amount of feedback about Â�improvements for the book. In addition, I appreciate the time scientists took to let us take photos and discuss their work with them. I admire and appreciate every one of you. If you would like to share your experience with chemistry or have questions and comments about this text, I would appreciate hearing from you. Karen Timberlake Email: [email protected]

Besser Konzepte und Ideen der organischen Chemie verstehen, als eine Vielzahl von Fakten auswendig beherrschen! Diesem Motto bleibt der "Vollhardt/Schore" auch in der neuesten Auflage treu. Das neu gestaltete Layout, beispielhaft gelöste Übungsaufgaben und die deutlich erweiterten Verständnisübungen führen einprägsam an die Methodik zur Lösung organisch-chemischer Probleme heran. So werden nicht nur die stofflichen Grundlagen der organischen Chemie, sondern auch das "Gewusst wie" fast schon spielerisch vermittelt. Nicht nur für Chemiestudenten, auch für Biochemiker, Pharmazeuten, Biologen und Mediziner ist der "Vollhardt/Schore" der fachliche Grundstock für die organische Chemie.

Wenn es knallt und stinkt, dann ist Chemie im Spiel! "Chemie für Dummies" macht deutlich, dass Chemie nicht nur aus Formeln, sondern vor allem aus unzähligen interessanten Stoffen, Versuchen und Reaktionen besteht. In diesem etwas anderen Chemie-Buch lernen Sie die Grundlagen der Chemie kennen und erfahren, wo sich chemische Phänomene im Alltag bemerkbar machen. John T. Moore macht für Sie so schwer vorstellbare Begriffe wie Atom, Base oder Molekül begreiflich und zeigt, wie man mit dem Periodensystem umgeht. Mit Übungsaufgaben am Ende eines jeden Kapitels können Sie dann noch Ihr Wissen überprüfen.
