Lesson 31: Alekenes & Alkynes (Double & Triple Bonds)

  • Carbon can form double & triple bonds with carbon atoms
  • When multiple bonds form fewer hydrogens 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 
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
