Physical Properties and State The physical state of an alkene at room temperature ranges from gas to liquid, depending primarily on the molecular weight. Unlike saturated hydrocarbons, which contain only single bonds, alkenes possess this double bond, making them unsaturated and highly reactive.
Detecting Alkene Functional Groups in Organic Molecules
Chemical Reactivity and Industrial Significance The chemical reactivity of alkenes is dominated by the electron-rich double bond, which acts as a nucleophile in reactions with electrophiles. Biological Origins and Natural Occurrence.
Substances like ethene and propene are polymerized to form plastics such as polyethylene and polypropylene, which constitute a massive portion of modern manufactured goods. The most common reaction is an addition reaction, where the pi bond breaks and atoms add across the double bond, converting the alkene into a saturated compound.

Furthermore, these molecules serve as crucial intermediates in the synthesis of alcohols, solvents, and pharmaceuticals. However, they tend to be quite flammable and possess distinct odors.
