a Alkenes are named according to a series of E. rules similar to those developed for alkanes a with the suffix-ene used to instead of -ane to y identify the family Step 1 Name the parent hydrocarbon m Step 2 Number the carbon atoms in the chain, beginning at the end nearer the double bond 3. Step 3 Write the full name. If more than one double bond is present, indicate the position of each and use the suffixes-diene -triene tetraene, and so on
