Alkenes: Formula And Examples In Chemistry

Alkenes are chemical elements with double bonds or carbon double bonds. Its general formula is the following: CnH2n. These atomic structures differ from alkanes by having a greater amount of hydrocarbons, which causes the hydrogen atoms to be reduced in their formulas.


The characteristics of alkenes do not allow their resistance to solid bonds, that is, they are hydrocarbons but to the extent that they create new carbon bonds, they subtract hydrogen atoms, so they become insoluble and cannot create bonds with elements such as nitrogen.

What is The difference between Alkanes vs Alkenes?

Both are chemical elements made up of carbon and hydrogen. Alkanes, for their part, are composed of hydrogen atoms while alkenes in their structure subtract soluble atoms.

Alkenes are called alkanes without hydrogen since their nuclear components remain the same, governed by carbon.

By strengthening the carbon bonds above the hydrogen bonds, they can structure themselves as hydrocarbon chemical elements.

5 Important Examples of alkenes In Chemistry

  1. Ethene or ethylene: Made up of two carbon atoms, it is one of the most famous alkenes used industrially for the manufacture of polyethylene. Ethylene is also a natural plant hormone that accelerates plant growth in stable temperatures, and is also used in fruits for ripening.
  2. Propene or propylene: like all alkenes, it has a double carbon bond. Alcohols are obtained from it.
  3. Butene or butylene: It is obtained from petroleum derivatives and is useful for the manufacture of flammable gases.
  4. Cyclopentene: It is obtained in a liquid state, similar to petroleum. It is used for the disintegration of plastics.
  5. Polyethylene: It is used to create plastics due to its malleability .
