IUPAC NOMENCLATURE OF ALKENES

To name alkenes:

1. Find the longest chain containing the alkene

2. Number the chain, giving the double bond the lowest possible number.

3. For cycloalkenes, begin numbering at the double bond and proceed through the double bond in the direction to generate the lowest number at the first point of difference.

4. Assign stereochemistry using the E-Z designation
