Dienes- Organic compound containing 2 separate carbon to carbon double bonds C=C
The rule for naming is they all end with "-diene".
The general formula is CnH2n-2, n is the number of carbons is used to determine the number of hydrogen atoms. Example n=4, so H=(2(4)-2)=6
Dienes are ISOMERS of Alkynes (same general formula)
Naming Compounds- Again, ignore all the hydrogen's. We only worry about carbon atoms.
Rule #1-Name the longest chain that contains both double bonds. End it with "diene".
Rule #2-When necessary use the lowest numbers to give the locations of both double bonds.
