Many fundamental concepts must be mastered before a student can make progress in organic chemistry. This book provides a relatively rigorous discussion of these underlying principles and can make a significant difference in the student's ability to learn organic chemistry. The progressive disclosure (programmed) style will contain short sections of material that will be followed by a question (and answer) that helps the student understand and master the material covered in that chapter. Many of these questions will also include sufficient review that makes the task of memorization easier, particularly for the nomenclature.
