Alkenes & Alkynes (double & triple bonds)- brian

- carbon can form double & triple bonds with carbon atoms

- when multiple bonds form fewer hydrogen's are attached to the carbon atom

- naming rules are almost the same as with alkanes
-the position of the double/triple bonds always has the lowest number and is put in front of the parent chain

- double bonds(Alkenes) end in ENE

- triple bonds(Alkynes) end in YNE

Example:

Trans & Cis butene
- if two adjacent carbons are bonded by a double bond and have side chains on them two possible compounds are possible
 

          














Multiple double bonds
- more than one double bond can exist in a molecule

- use the same multipliers inside the parent chain

Example:
