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.

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.

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

Dec 1, 2022 · When there are two or three double bonds in a molecule, the ending -ane of the corresponding alkane is replaced by ‘-adiene’ or ‘atriene’ to get the name of the alkene.

There are two factors to consider when deciding the more stable alkene. One is the sterics which is expressed when comparing cis and trans isomers – trans alkenes are more stable because …

May 2, 2025 · The most basic alkene is ethene (C₂H₄), which has two carbon atoms connected by a double bond and each carbon bonded to two hydrogens. Alkenes can also be branched or …
