One carbon atom and two oxygen atoms make up carbon dioxide. One carbon atom and one oxygen atom make up carbon monoxide. Carbon dioxide is a non-toxic gas that is naturally present in the atmosphere and is excreted by animals and people. Carbon mono-oxide is a non-toxic gas formed by incomplete combustion of organic molecules. It does not occur naturally in the atmosphere. Carbon dioxide is a non-flammable gas, but carbon monoxide is.
The surprising resemblance in their name is due to chemistry naming rules. The name distinction comes from the fact that monoxide has only one oxygen atom opposed to two in a dioxide molecule. However, this does not imply that they are identical. There are some significant variations in terms of safety.
Carbon Dioxide
CO2 is a chemical molecule that consists of one carbon atom and two oxygen atoms. At room temperature, it is an odourless and colorless gas that is found in low concentration in the Earth’s atmosphere. CO2 is released into the atmosphere by organisms’ respiration, breakdown of organic matter, fossil fuel combustion, and fermentation. It is a greenhouse gas that traps heat energy within the earth’s atmosphere and contributes to global warming. It is taken in by plants via the process of photosynthesis and can be hazardous to the environment. CO2 is used for a variety of purposes, including freezing food, carbonating beverages, extinguishing fires, and numerous agricultural and medical uses.
Carbon Monoxide
Carbon monoxide (CO) is a colourless and odourless gas made up of one carbon atom and one oxygen atom. Unlike CO2 , it is completely man-made and does not occur naturally in the atmosphere. It is formed when carbon-based fuels are used in automobiles, heaters, or culinary equipment, resulting in incomplete combustion of organic materials. CO is thus geographically varied and short-lived in the atmosphere, where it contributes to the formation of ozone at ground level. Carbon monoxide is hazardous to people and animals at quantities more than 35ppm because it stops the blood from transporting oxygen.
Main uses of Carbon dioxide and Carbon monoxide detection
Carbon dioxide detection is important in a variety of industries, including HVAC, landfills, horticulture, controlled environment storage and packing, metal heat treatments, TOC, and many more. Without precision CO2 monitoring, none of these applications would be viable. If you are interested in learning more about specific CO2 sensing application, check out the following articles…

Because detection cannot be done solely by vision or smell, carbon monoxide sensing using a CO sensor is equally crucial. It is required because carbon monoxide poisoning can result in loss of consciousness, seizures, and even death. CO sensing is also used in a variety of other applications, which you may learn more about by clicking on the links below.

Difference between Carbon dioxide and Carbon monoxide
| Carbon Dioxide | Carbon Monoxide |
| Carbon dioxide is composed of a carbon atom bonded to two oxygen atoms. | Carbon monoxide is composed of a carbon atom bonded to one oxygen atom. |
| Molar mass is about 44g/mol | Molar mass is about 28g/mol |
| Bond length between carbon and oxygen is about 116.3pm | Bond length between carbon and oxygen is about 112.8pm |
| There is a covalent double bond between carbon and oxygen. | There is a covalent double bond as well as a coordination bond between carbon and oxygen. |
| Produced in the complete combustion of fossil fuels. | Produced in the incomplete combustion of fossil fuels |
| Can not undergo oxidation reaction. | Can undergo oxidation reaction. |
Carbon monoxide and carbon dioxide detector
To detect quantities of gas in the environment, carbon dioxide detectors employ infrared sensors, whereas carbon monoxide detectors use electrochemical sensors, gel sensors, and metal oxide semiconductors.
Bond strength of carbon monoxide and carbon dioxide
Carbon and oxygen have a bond length of roughly 112.8pm, which is shorter than carbon dioxide because carbon dioxide has a double bond between carbon and oxygen but carbon monoxide has a triple bond. The triple bond binds the two atoms more securely than a double bond, resulting in a shorter bond length.
The carbon monoxide molecule has a tiny dipole moment because the oxygen atom is more electronegative than the carbon atom. However, because there is a coordination link that gives electrons to the carbon, it is not a strong dipole.
Conclusion
Carbon dioxide is made up of one carbon atom and two oxygen atoms. Carbon monoxide is made up of one carbon atom and one oxygen atom. Carbon dioxide is a non-toxic gas found naturally in the atmosphere and excreted by both animals and humans. Carbon mono-oxide is a non-toxic gas produced when organic molecules are incompletely burned. It isn’t found in the atmosphere naturally. Although carbon dioxide is not flammable, carbon monoxide is.
The startling similarity in their names is owing to the naming laws of chemistry. The difference in nomenclature arises from the fact that monoxide has only one oxygen atom, whereas dioxide has two.
