The general suffix for a compound with a carbon-carbon double bond is "ene" as
in "propene". The "diene" refers to the fact that there are two double bonds
in the main chain.
The 1,3- part tells you where the double bonds are: they are between carbon atoms 1 and 2, and between carbon atoms 3 and 4. This is the same principle as "3-isopropyl" (not isopropAl!), the "3" tells you where the point of attachment is. For more, see David Woodcock's excellent organic nomenclature website. Dan Berger |
