How do you name cycloalkenes?
Naming Rules
Cycloalkenes are named the same way that open chain chained alkenes are, with the exception that the numbering is started at one of the carbons of the double bond in order to keep the index numbers as small as possible.
How do you name cycloalkynes?
To name a cycloalkyne.
- Count the number of carbon atoms in the ring.
- Name the ring as a cycloalkyne.
- Number the triple-bonded carbon atoms as C1 and C2.

- List substituents in alphabetical order.
- Use multiplying prefixes to show the number of triple bonds.
