			Alkanes can be recognized by their '''-ene''' suffix.

			When there are 4 or more carbons in a chain, the position of the double bond can create different possible structures and uses a more precise nomenclature. Compounds that have the same chemical formula but have different bonding arrangements are called [[chemical isomer\|structural isomers]].

<onlyinclude>An '''alkene''' is one of the four main types of [[hydrocarbon]]s. Alkenes are true hydrocarbons, meaning they are made up of nothing but [[hydrogen]] and [[carbon]].</onlyinclude><ref>http://chemwiki.ucdavis.edu/Organic_Chemistry/Hydrocarbons/Alkenes</ref>

Alkanes are based on the formula <m>C_nH_{2n}</m>.
*<m>C</m> is Carbon.
*<m>H</m> is Hydrogen.
*<m>n</m> refers to the number of [[molecule]]s.

Alkenes are similar to [[Alkane]]s except they contain a double bond between two carbon atoms. When one carbon shares a double bond with another, this limits the number of hydrogen which can be bonded (resulting in less hydrogen atoms per carbon atom).

Examples are ethene (<m>C_{2} H_{4}</m>), propene (<m>C_{3} H_{6}</m>) and butene (<m>C_{4} H_{8}</m>). Note that when we have 4 or more carbon in a chain, the position of the double bond can create different possible structures and uses a more precise nomenclature.
