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!

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.

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 …

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 …

Alkene reactions Learn Introduction to reaction mechanisms Markovnikov's rule and carbocations

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 > …

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 …

Ethylene: A space-filling model of ethylene, the simplest alkene, showing its planar structure. Alkenes contain a double bond that is composed of one sigma and one pi bond between two carbon atoms.

In organic chemistry, an alkene, olefin, or olefine is an unsaturated chemical compound containing at least one carbon -to- carbon double bond. [1] The simplest alkenes, with only one double bond, no …
