Pentene - Wikipedia
1-Pentene is an alpha-olefin. Most often, 1-pentene is made as a byproduct of catalytic or thermal cracking of petroleum or during the production of ethylene and propylene via thermal cracking of hydrocarbon fractions.

The longest chain containing the double bond has five carbon atoms, so the compound is a pentene (rule 1). To give the first carbon atom of the double bond the lowest number (rule 2), we number from the left, so the compound is a 2-pentene. There is a methyl group on the fourth carbon atom (rule 3), so the compound’s name is 4-methyl-2-pentene.

Pentene | Formula, Properties & Application
Pentene is a series of unsaturated hydrocarbons belonging to the alkene group, an important family of organic compounds. In particular, pentene refers to the alkenes with the chemical formula C 5 H 10 .
7.4: Naming Alkenes - Chemistry LibreTexts
2024年10月12日 · Alkenes contain carbon-carbon double bonds and are unsaturated hydrocarbons with the molecular formula is C n H 2n; this is also the same molecular formula as cycloalkanes. The parent chain of an alkene is the longest chain containing both carbon atoms of the double bond.
Nomenclature of Alkenes - Chemistry LibreTexts
2023年1月23日 · The formula of the five-carbon alkane pentane is C5H12 C 5 H 12 so the difference in hydrogen content is 4. This difference suggests such compounds may have a triple bond, two double bonds, a ring plus a double bond, or two rings. Some examples are shown here, and there are at least fourteen others!
