This class of unsaturated organic molecules forms the foundation for a vast array of industrial polymers and fine chemicals, making their study essential for understanding modern synthetic chemistry. Unlike alkanes, which are saturated with hydrogen, alkenes possess regions of higher electron density due to the pi bond, rendering them susceptible to addition reactions.

The general molecular formula for acyclic alkenes is CnH2n, indicating a degree of unsaturation compared to the corresponding alkane. Occurrence and Industrial Synthesis While alkenes are found naturally in trace amounts in petroleum and certain plant hormones, the vast majority used in industry are produced through large-scale refining processes.
The pi electrons are exposed and easily attacked by electrophiles, making these compounds highly reactive in addition reactions. As a result, tetrasubstituted alkenes are thermodynamically favored over monosubstituted ones in equilibrium mixtures.

Furthermore, these compounds are categorized as mono-, di-, or poly-unsaturated depending on the number of double bonds present. More substituted alkenes, where the carbon atoms of the double bond are bonded to more carbon groups, are significantly more stable than their less substituted counterparts.
