Organic chemistry is one of two fairly distinct parts of chemistry, the other being inorganic chemistry. It is generally studied separately from inorganic chemistry and, above a certain level, students use different textbooks for the two branches of the discipline. The Facts On File Dictionary of Organic Chemistry provides quick access and complete reference definition to the terms, concepts, and principles that make up a significant part of section 4 of the advanced placement chemistry course for high school students. Undergraduate chemistry students and students studying the life sciences will also find this volume useful. Areas of the subject covered include basic terms in chemistry: physical chemistry; techniques used in organic chemistry; elements; classes of compounds; named compounds; and industrial processes.
