To understand the chemistry of life, we must understand the chemistry of tiny molecules. This book will provide a platform to understand the molecular level of chemistry. It will touch the reality of chemistry, which is almost a mystery. The books will stimulate the readers to enter the world of molecules, where they will experience molecular movements, for the making of bonds or breaking of bonds. The purpose of this book is to make the bonding of students with chemistry; it will work as a catalyst to enhance the rate of understanding the reaction mechanism with the logical concept. No one will force the student to read this book; His interest will insist him to read this book. It is the actual pathway to get the skill. Don't kill your skill.
