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. Stability and Substituent Effects The stability of alkenes is heavily influenced by the substitution pattern around the double bond.

Furthermore, these compounds are categorized as mono-, di-, or poly-unsaturated depending on the number of double bonds present. Additionally, these hydrocarbons are typically non-polar and insoluble in water, but they dissolve readily in non-polar organic solvents like hexane and benzene.
This stability arises from hyperconjugation and the inductive effects of alkyl groups, which help to disperse the electron density of the pi bond. Physical Properties and Trends The physical properties of alkenes follow predictable trends based on molecular size and structure.

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. Conversely, internal alkenes feature the double bond further along the chain, which can influence the molecule's stability and physical state.
