What is the chemical formula for Carbon Monoxide?

The chemical formula for Carbon Monoxide is CO. This formula indicates that each molecule of carbon monoxide is made up of one carbon atom and one oxygen atom. The naming conventions in chemistry dictate that the "C" stands for carbon and the "O" for oxygen.

Understanding this molecular structure is important because it highlights the nature and behavior of carbon monoxide as a gas that is produced by incomplete combustion. In contrast, the other options either represent different compounds or have incorrect counts of atoms: CO₂ represents carbon dioxide, C₂O suggests a compound with two carbon atoms and one oxygen (not carbon monoxide), and CHO relates to chemical compounds containing carbon, hydrogen, and oxygen, commonly found in organic chemistry as part of functional groups or larger molecules.
