Carbon monoxide, with the chemical formula CO, is a colorless, odorless, and tasteless gas . It is the product of the partial combustion of carbon -containing compounds, notably in internal-combustion engines . Carbon monoxide forms in preference to the more usual carbon dioxide when there is a reduced availability of oxygen present during the combustion process. Carbon monoxide has significant fuel value, burning in air with a characteristic blue flame, producing carbon dioxide . Despite its serious toxicity , CO plays a highly useful role in modern technology, being a precursor to a myriad of products. It consists of one carbon atom covalently bonded to one oxygen atom. It is a gas at room temperature.
