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.

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 > …

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 …

5 days ago · alkene (plural alkenes) (organic chemistry) An unsaturated, aliphatic hydrocarbon with one or more carbon–carbon double bonds.

Nov 14, 2017 · One of the common synthesis of alkene is by the elimination reaction from alkyl halide, alcohol and similar compound. Alkenes perform many addition reactions via the mechanism of …

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 boiling point of each alkene is very similar to that of the alkane with the same number of carbon atoms. Ethene, propene and the various butenes are gases at room temperature.

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 …
