Octane is used as a fuel and as a raw material for building more complex organic molecules. It is the eighth member of the alkane series. Organic compounds were once thought to be produced only by living things.
Organic chemistry is concerned with the compounds of carbon.
Biochemistry is concerned with compounds of carbon that crawl. Alkanes are usually asymmetric but are nonpolar because they contain no polar bonds. A polyatomic molecule is a particle that contains more than two atoms. A colorless, odorless, flammable gas, found in petroleum and natural gas.
