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.

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 have …

Ethene is an alkene with an E-N-E ending, and it has the molecular formula C2H4. For two carbons, six hydrogens is the maximum number that you can have, so we say that ethane is completely saturated …

So, the more electron-donating alkyl groups on the C=C carbon atoms, the more stable the alkene. Therefore, we have this pattern of stability: Tetrasubstituted > Trisubstituted > Disubstituted > …

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 …

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 …
