What is typically produced when alkenes undergo incomplete combustion?

When alkenes undergo incomplete combustion, the primary products are soot and carbon monoxide. Incomplete combustion occurs when there is insufficient oxygen available for the alkene to react completely. As a result, instead of producing carbon dioxide and water—typical products of complete combustion—some of the carbon atoms in the alkene do not fully oxidize, leading to the formation of solid carbon particles, or soot, and carbon monoxide, a harmful gas.

This reaction illustrates the importance of sufficient oxygen supply in combustion processes. In environments with limited oxygen, the efficiency of fuel burning decreases, and more dangerous byproducts are generated. Understanding the differences between complete and incomplete combustion is crucial for grasping the environmental impacts of various fuels and their combustion products.
