Objective

After completing this section, you should be able to give an example of a naturally occurring compound that contains at least one double bond.

Key Terms

Make certain that you can define, and use in context, the key term below.

olefin

Study Notes

Alkenes are a class of hydrocarbons (i.e., containing only carbon and hydrogen). They are unsaturated compounds with at least one carbon-to-carbon double bond. The double bond makes Alkenes more reactive than alkanes. Olefin is another term used to describe alkenes.

The graphic (structure 7-0) shows three alkenes. The more complex alkene is commonly known as 1-methene, but its full proper IUPAC name is 1-methyl-2-(1-methylethyl)-cyclohexene.
