In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon –carbon double bond. [1] The double bond may be internal or at the terminal position.

Read this tutorial for help on alkene! We will provide you with its properties, structure, nomenclature, and reactions!

They are unsaturated compounds with at least one carbon-to-carbon double bond. The double bond makes alkenes more reactive than alkanes. Olefin is another term used to describe alkenes. The …

Apr 22, 2022 · Alkenes are unsaturated hydrocarbons containing carbon-carbon double bonds. The general formula of an alkene is CnH2n.

Where is alkene found? Alkenes are the raw materials for plastics such as polyethene, PVC, polypropylene, and polystyrene, among others. The chemistry of alkenes is present in unsaturated …

The vitamin A precursor found in both spinach and bell peppers is beta-carotene, an alkene. Beta-carotene consists of a long carbon chain with multiple double bonds with a substituted cyclohexene …

An alkene refers to a class of unsaturated hydrocarbons that contain at least one carbon-carbon double bond. They fit into the group of organic compounds called unsaturated hydrocarbons and are …

The double-bonded carbons of an alkene are electron-rich, that is, the electron density is high in the region of the double bond. Therefore, the “signature” reaction of alkenes involves initial attack on an …

Jan 19, 2026 · Revision notes on Alkenes for the Cambridge (CIE) IGCSE Combined Science syllabus, written by the Science experts at Save My Exams.

The name alkene (with suffix ~ene) as opposed to alkane, implies that a carbon to carbon double bond will be found within the organic molecule. Alkenes play a major role in modern and biological chemistry.
