The Ninth Edition of Organic Chemistry continues Solomons-Fryhle's tradition of excellence in teaching and preparing students for success in the organic classroom and beyond.Students are often overwhelmed by the early rigors of organic chemistry. Solomons-Fryhle prepares students for these early rigors by introducing acids & bases--topics they know from general chemistry--early, followed by chapters on structure and stereochemistry. Next, a discussion of ionic reactions gives students a foundation for the vast majority of reactions that they will encounter. The Ninth Edition continues to introduce IR spectroscopy in chapter 2 (after functional groups) and Carbon-13 NMR spectroscopy in chapter 4, providing synergy with most lab courses and, again, reinforcing learning.The new edition of Solomons-Fryhle also has a completely revised WileyPLUS course to help students and instructors reach their full potential. WileyPLUS provides instructors with the most robust online homework solution in organic chemistry. This revision of WileyPLUS meets students where and when they learn and provides them with a learning platform that offers real learning solutions that complement their approach to managing and mastering organic concepts.
