Examples of Alkenes in the following topics:
-
- Alkenes contain a double bond that is composed of one sigma and one pi bond between two carbon atoms.
- Alkene isomers that can achieve more regular packing have higher melting and boiling points than molecules with the same molecular formula but weaker dispersion forces.
- Alkenes are non-polar, and they are both immiscible in water and less dense than water.
- Alkenes are more reactive than their related alkanes due to the relative instability of the double bond.
- Alkenes can also be reacted, typically in the presence of a catalyst, to form polymers.
-
- Alkenes and alkynes are hydrocarbons which respectively have carbon-carbon double bond and carbon-carbon triple bond functional groups.
-
- Alkenes and alkynes are named similarly to alkanes, based on the longest chain that contains the double or triple bond.
- Alkenes are hydrocarbons that contain one or more double bonds, while alkynes contain one or more triple bonds.
- Alkene and alkyne compounds are named by identifying the longest carbon chain that contains both carbons of the double or triple bond.

-
- Alkenes and alkynes are more reactive than alkanes due to their pi bonds.
- Alkenes and alkynes are generally more reactive than alkanes due to the electron density available in their pi bonds.
- Alkenes undergo diverse cycloaddition reactions.
- Alkenes and alkynes can also be halogenated with the halogen adding across the double or triple bond, in a similar fashion to hydrogenation.
- Alkenes and alkynes can react with hydrogen halides like HCl and HBr.
-
- In the isomers illustrated under Configurational Stereoisomers of Alkenes, for which cis-trans notation was adequate, Z is equivalent to cis and E is equivalent to trans.
-
- Alkenes and alkynes are known as unsaturated hydrocarbons because some of the carbons are connected to fewer than four neighboring atoms.
- Alkenes contain at least one double bond, while alkynes contain at least one triple bond.
