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.

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

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 …

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 > …

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 …

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.

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 …
