The Study of Carbon-containing compounds and their properties is called organic chemistry. However, few compounds of carbon such as carbon dioxide, carbon monoxide, carbonates, and carbides are considered to be inorganic substances. This is because they have totally different properties than organic compounds. Organic compounds play a vital role in the bodies of living things. Products of industrial organic chemistry such as plastics, rubber, synthetic fibers, paints, glues, varnishes, artificial sweeteners and flavors, drugs, dyes, soaps, and detergents, etc. are an important part of modern life. Also, the energy on which we rely heavily is based mostly on organic materials found in coal, petroleum, and natural gas.
