Monoene

Monoene is a term used in organic chemistry to describe a molecule that contains a single carbon-carbon double bond. This functional group, also known as an alkene, is characterized by the presence of a pi bond in addition to a sigma bond between two carbon atoms. Monoenes are unsaturated hydrocarbons, meaning they have fewer hydrogen atoms than their corresponding saturated alkanes. The general formula for a monoene with one double bond and no rings is CnH2n. The presence of the double bond makes monoenes more reactive than alkanes, particularly in addition reactions where the pi bond can be broken to form new single bonds with other atoms or molecules. Examples of simple monoenes include ethene (C2H4) and propene (C3H6). These compounds are important building blocks in the petrochemical industry and are used in the synthesis of polymers, plastics, and other organic chemicals. The position of the double bond within a carbon chain is a key factor in determining the chemical and physical properties of a monoene.
