Alkenes and Alkynes (double&triple bonds)


  • carbon can form double and triple bonds with carbon atoms
  • naming rule  --the position of the double/triple bonds always have the lowest number and is out in front of the parent chain
  • double bonds (alkenes) end in -ene
  • triple bonds (alkynes) end in -yne
EX.


5, 5 diethyl 2,6,7 trimethyl 3 octene
Ethene

4 methyl 2 pentyne



















Multiple Double Bonds
  • more than one double bond can exist in a molecule
  • you can use the same multipliers inside the parent chain
