Professor Felix Carroll has completed the second edition of his textbook Perspectives on Structure and Mechanism in Organic Chemistry, which was published by Wiley in mid-July. The book jacket praises Carroll's use of complementary conceptual models in order to provide new perspectives on the structures and reactions of organic compounds. Its first five chapters discuss structure and bonding of stable molecules and reactive intermediates; chapter 6 explores the methods that organic chemists use to study reaction mechanisms; and the remaining six chapters examine different types of acid-base, substitution, addition, elimination, pericyclic, and photochemical reactions. The text's nearly 400 problems not only enable students to test their understanding of each chapter's concepts, but also encourage them to actively review and evaluate chemical literature in order to develop and defend their own ideas.
