Organic compounds are, at the most basic level, compounds that contain carbon and hydrogen. These compounds are called organic because they were once believed to have been derived from living things, but that is not necessarily the case. The organic compound is a large class of chemical compounds in which one or more carbon atoms are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. Some examples of organic compounds are carbohydrates, fats (lipids), proteins, and nucleic acids, which are the basis for the molecules of life. “Classification & Analysis of Organic Compounds” is a comprehensive book that describes basic concepts about the classification of organic compounds and how to do analysis of an organic compound. The book includes crystallization techniques, concepts of photochemistry, the chemistry of volatile organic compounds, electrochemistry, medicinal organic chemistry, enzymes, and their action. This book includes concepts about intermolecular interactions and their significance in detail.
