Nomenclature of Alkenes
•Ethylene is an acceptable synonym for ethene in the IUPAC system
•Propylene, isobutylene and other common names ending with
“ylene” are NOT accepted by IUPAC
The IUPAC name of an alkene is obtained by replacing the “ane”
ending of the corresponding alkane with “ene”

Determine the parent
hydrocarbon –the longest
continuous carbon chain
containing the C=C

Note: Alkenes may have geometric isomers
