As with any functional group there is a list of rules that must be followed for naming alkenes. 

Naming Alkenes

Concept #1: Rules for Naming Alkenes

Example #1: Naming the following alkene compound. 

Example #2: Naming the following alkene compound. 

Example #3: Determine the structure for the following alkene compound.

5-bromo-4,4-dimethyl-2-heptene

Example #4: Determine the structure for the following alkene compound.

2, 5–octadiene 

Example #5: Determine the structure for the following alkene compound.

Trans–3–hexene

Additional Problems
Provide the structural formula based on the given name.  a) 2-Fluoro-1,3-butadiene     b) 1-bromo-5-chloro-2-hexene
An organic compound contains 2 carbon atoms and one double C=C bond would have the name of: a) Propane b) Butene c) Butane d) Ethene
Name the following alkene.  
NAMING ALKENES Naming an alkene is similar to naming an alkane with a few differences. Find the longest carbon chain and change the “ane” ending to “ene”. If there is a tie between longest chains, choose the chain that gives the __________ substituents. Number the chain from the end closest to the double bond and provide a number for its location.    Substituents will be named alphabetically and a number will accompany the location of their attachment. If more than one of a similar alkyl group is present then we must use numerical prefixes to describe the number of them. __________ – 2           __________ – 3           __________ – 4           __________ – 5
