This book is intended for a short course in introductory organic chemistry for students specializing in health science, health technology, nursing, nutrition, agriculture, veterinary science and forestry. Following a brief review of structure and bonding, organic molecules and functional groups are presented as early as possible. The text is organized primarily by functional group, beginning with simple alkanes and moving toward more complex compounds. Emphasis is placed on the fundamental mechanistic similarities of organic reactions. The author's revision continues to present the content necessary for this course without sacrifice of important subjects and pedagogical tools. Text and reaction summaries, full problem sets, and artwork are also featured in the third edition.
