    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.
