Sets forth the analytical tools needed to solve key problems in organic chemistry With its acclaimed decision-based approach, Electron Flow in Organic Chemistry enables readers to develop the essential critical thinking skills needed to analyze and solve problems in organic chemistry, from the simple to complex. The author breaks down common mechanistic organic processes into their basic units to explain the core electron flow pathways that underlie these processes. Moreover, the text stresses the use of analytical tools such as flow charts, correlation matrices, and energy surfaces to enable readers new to organic chemistry to grasp the fundamentals at a much deeper level. This Second Edition of Electron Flow in Organic Chemistry has been thoroughly revised, reorganized, and streamlined in response to feedback from both students and instructors. Readers will find more flowcharts, correlation matrices, and algorithms that illustrate key decision-making processes step by step. There are new examples from the field of biochemistry, making the text more relevant to a broader range of readers in chemistry, biology, and medicine. This edition also offers three new chapters: Proton transfer and the principles of stability Important reaction archetypes Qualitative molecular orbital theory and pericyclic reactions The text's appendix features a variety of helpful tools, including a general bibliography, quick-reference charts and tables, pathway summaries, and a major decisions guide. With its emphasis on logical processes rather than memorization to solve mechanistic problems, this text gives readers a solid foundation to approach and solve any problem in organic chemistry.

Involved as it is with 95% of the periodic table, inorganic chemistry is one of the foundational subjects of scientific study. Inorganic catalysts are used in crucial industrial processes and the field, to a significant extent, also forms the basis of nanotechnology. Unfortunately, the subject is not a popular one for undergraduates. This book aims to take a step to change this state of affairs by presenting a mechanistic, logical introduction to the subject. Organic teaching places heavy emphasis on reaction mechanisms - "arrow-pushing" - and the authors of this book have found that a mechanistic approach works just as well for elementary inorganic chemistry. As opposed to listening to formal lectures or learning the material by heart, by teaching students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing, this book serves as a gentle and stimulating introduction to inorganic chemistry, providing students with the knowledge and opportunity to solve inorganic reaction mechanisms. • The first book to apply the arrow-pushing method to inorganic chemistry teaching • With the reaction mechanisms approach ("arrow-pushing"), students will no longer have to rely on memorization as a device for learning this subject, but will instead have a logical foundation for this area of study • Teaches students to recognize common inorganic species as electrophiles and nucleophiles, coupled with organic-style arrow-pushing • Provides a degree of integration with what students learn in organic chemistry, facilitating learning of this subject • Serves as an invaluable companion to any introductory inorganic chemistry textbook

Make the leap from introductory to organic chemistry The transition from first-year chemistry to an organic chemistry course can be a challenge for many students. Not only must they recall their first-year studies of bonding, structure, and reactivity, but they must also master a whole new set of nomenclature, along with the critical skill of "electron-pushing." Reviewing the fundamentals and carefully introducing the important new concepts, The Bridge to Organic Chemistry: Concepts and Nomenclature helps students smoothly bridge the gap to organic chemistry. Concise and carefully structured, The Bridge to Organic Chemistry helps students strengthen their mastery of fundamental concepts from an introductory chemistry course and then introduces them to the new concepts of organic chemistry. Step by step, the reader will: Review important concepts such as structural isomerism, Lewis formulas, hybridization, and resonance and understand their roles in modern organic chemistry Learn organic nomenclature along with the critical skill of "electron-pushing" Explore mechanisms that utilize many of the concepts: Lewis acid-base chemistry, rate laws, enthalpy changes, bond energies and electronegativities, substituent effects, structure, stereochemistry, and the visualization of electron flow through the electron-pushing model With a clear progressive style and substantial review at each step, The Bridge to Organic Chemistry puts organic chemistry and its nomenclature within the grasp of every student.

As the amount of information in biology expands dramatically, it becomes increasingly important for textbooks to distill the vast amount of scientific knowledge into concise principles and enduring concepts.As with previous editions, Molecular Biology of the Cell, Sixth Edition accomplishes this goal with clear writing and beautiful illustrations. The Sixth Edition has been extensively revised and updated with the latest research in the field of cell biology, and it provides an exceptional framework for teaching and learning. The entire illustration program has been greatly enhanced.Protein structures better illustrate structure–function relationships, icons are simpler and more consistent within and between chapters, and micrographs have been refreshed and updated with newer, clearer, or better images. As a new feature, each chapter now contains intriguing openended questions highlighting “What We Don’t Know,” introducing students to challenging areas of future research. Updated end-of-chapter problems reflect new research discussed in the text, and these problems have been expanded to all chapters by adding questions on developmental biology, tissues and stem cells, pathogens, and the immune system.

From the best-selling, award-winning author of 1491 and 1493--an incisive portrait of the two little-known twentieth-century scientists, Norman Borlaug and William Vogt, whose diametrically opposed views shaped our ideas about the environment, laying the groundwork for how people in the twenty-first century will choose to live in tomorrow's world. In forty years, Earth's population will reach ten billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups--Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin. Cut back! was his mantra. Otherwise everyone will lose! The Wizards are the heirs of Norman Borlaug, whose research, in effect, wrangled the world in service to our species to produce modern high-yield crops that then saved millions from starvation. Innovate! was Borlaug's cry. Only in that way can everyone win! Mann delves into these diverging viewpoints to assess the four great challenges humanity faces--food, water, energy, climate change--grounding each in historical context and weighing the options for the future. With our civilization on the line, the author's insightful analysis is an essential addition to the urgent conversation about how our children will fare on an increasingly crowded Earth.
