This is when there is not enough oxygen available for a fuel to burn fully and form carbon dioxide and water. As a result, the poisonous gas, carbon monoxide may be formed or even just carbon on its own (soot).

incomplete combustion is when the fuel does not burn in sufficient oxygen and therefore produces carbon monoxide, carbon in the form of soot and water

Incomplete combustion is what happens when there isn't enough oxygen or the supply of oxygen is poor. Whereas in normal (complete) combustion you would have the following equation:


hydrocarbon + oxygen -> water + carbon dioxide


in incomplete combustion you would have:


hydrocarbon + oxygen -> carbon monoxide + carbon + water


because there isn't enough oxygen to make both the water and carbon dioxide. This means that carbon monoxide gets made instead and, if there's any carbon left when all the oxygen is used it becomes soot.


Hope this helps!

Incomplete combustion is when the oxygen supply for the reaction is limited.


Water is still produced but instead of carbon dioxide, the odourless toxic gas carbon monoxide is produced.

when a fuel burn in limited supply of oxygen it will produce carbon monoxide and water

In normal or complete combustion with lots of oxygen around ( called excess oxygen) all hydrocarbon fuels burn to give just carbon dioxide and water. However, when there is not enough oxygen around this is called incomplete combustion and either carbon monoxide (C0) or carbon or a mixture of the two are produced. A good example of incomplete combustion is to watch a bunsen burner burning with a sooty ( yellow/orange) flame. To do this you need the air-hole closed. If you put the flame up against a flame proof mat you will see the soot ( carbon) of incomplete combustion quickly starting to form.

This is where there is a limited oxygen supply, less than required. So carbon monoxide is produced alongside carbon dioxide and water. So there are three products in the equation compared to two in complete combustion.

Chris Enos Best Answer!

Fuels are normally hydrocarbons - molecules that are made up of only atoms of hydrogen and carbon. When these fuels combust, these atoms react with the oxygen in the air to form oxides.


Hydrogen atoms will form water molecules

Carbon atoms will either form carbon monoxide or carbon dioxide


If there is plenty of oxygen then carbon will form carbon dioxide and we call this complete combustion. If there is not enough oxygen then carbon can only form carbon monoxide and we call this incomplete combustion.


Incomplete combustion is particularly dangerous as carbon monoxide is toxic and can cause death.

It is when there is not enough oxygen produced. Therefore, carbon monoxide (a toxic gas) is produced instead.

When substances have reacted with insufficient oxygen and will produce carbon monoxide (CO) and water (H2O).

Incomplete combustion is when there is insufficient oxygen for burning and carbon monoxide and carbon (soot) is produced as well as carbon dioxide. Complete combustion , if possible, would produce only carbon dioxide.

Incomplete combustion takes place when there is insufficient oxygen to supply to the fuel being burnt. It results in carbon monoxide and soot being formed instead of carbon dioxide. Water is also produced as well a reduced amount of energy liberated.

This is when there is little or no oxygen available for combustion so instead of carbon dioxide being produced carbon monoxide is, this is poisonous.

Smawar Waraich Best Answer!

A combustion reaction that takes places in an environment where there is not enough oxygen supply to react with all carbon atoms. Therefore, instead of producing carbon dioxide (CO2) as one of the products, it produces either carbon monoxide (CO) or carbon particulates (C) along with water (H2O)

Alin Best Answer!

Burning of fuels when there is poor oxygen. Results in the production of carbon monoxide
