A 3D model of ethylene, the simplest alkene. In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. [1] The double bond may be internal or in the terminal position. Terminal alkenes are also known as α-olefins.

2024年4月28日 · Although there is only one alkene with the formula C 2 H 4 (ethene) and only one with the formula C 3 H 6 (propene), there are several alkenes with the formula C 4 H 8. Here are some basic rules for naming alkenes from the International Union of Pure and Applied Chemistry (IUPAC):

2023年12月1日 · It is the most important alkene and is used in the production of a variety of petrochemicals, including plastics, polyethylene, and ethylene glycol. Ethene is also used as a ripening agent for fruits and vegetables. 2. Propene. Propene (C 3 H 6) is a colorless, odorless gas that is highly flammable. It is used in the production of a variety of ...

Alkene - Alkenes are hydrocarbons with the formula CnH2n. Alkenes contain the C=C functional group. Alkenes are unsaturated and undergo addition reactions. Other molecules add to the C=C bond.

Alkene Structure. Alkenes are hydrocarbons (compounds consisting entirely of carbon and hydrogen) that contain a carbon-carbon double bond (C=C, where one bond is a sigma bond, and the other a pi bond). The carbon-carbon double bond is the functional group of an alkene. The general structure of an alkene The structure of ethylene, the simplest ...

2022年12月1日 · What is an alkene? Alkenes are hydrocarbons that contain a carbon-carbon double bond (=C=C=) in their molecule. Alkenes are commonly known as olefins (in Latin, olefins mean “oil-forming) because the lower member of the …

2022年4月22日 · Alkenes are unsaturated hydrocarbons containing carbon-carbon double bonds. The general formula of an alkene is CnH2n.
