This book is part 1 of a two-part series covering undergraduate-level organic chemistry. If you’re enrolled in an organic chemistry course and need help understanding the concepts, this two-part series will help you with your goal. If you’re planning on enrolling in an organic chemistry course and would like to get a head start, this book is made for you. This series was written in such a way that it remains as detailed as a traditional textbook but looks and reads like detailed class notes. Everything is hand-drawn and written. Throughout the book there are detailed explanations walking the reader through the reasoning of every statement, reaction, mechanism, etc. The goal is to assist you in understanding the concepts instead of memorizing. This text is divided into 29 lectures.
