Organic chemistry, also known as carbon compound chemistry, is a very important branch of chemistry, which studies the composition, structure, properties, preparation methods and applications of organic compounds. Carbon-containing compounds are called organic compounds because previous chemists thought that carbon-containing substances must be made by organisms. However, in 1828, German chemist Friedrich W?hler successfully synthesized urea (a biomolecule) in the laboratory for the first time. Since then, organic chemistry has broken away from the traditional definition and expanded to the chemistry of carbon-containing substances.
