Organic Chemistry [PDF ebook] 
Fundamentals and Concepts

This book is intended for beginning students, both chemistry majors and other students who require it for their program. The material is presented in a concise and student-friendly way, without the inclusion of topics unnecessary at that level. A complete section is designed to lead students through the naming of organic compounds in a self-taught manner. Reactions are grouped by mechanistic type and stereochemistry is emphasized throughout. An introduction to the spectroscopic methods used for structure determination is included. Problems are included at each stage and new in this edition are complete answers to the problems as well as an introduction to the molecules of nature.
