2.  1. Start by Counting the number of Carbons in the longest chain. Be careful of bent molecules.  2. Find the appropriate prefix (Table P).  3. Look for any double bonds, triple bonds, or functional groups. If there are some, so to next slide (step 5).  4. If there are no extras on the molecule add the suffix “ane”.

3.  5. If there is a functional group, go to the next slide (step 9).  6. If there is a double bond, use the prefix from step 2 and add the suffix “ene”  7. If there is a triple bond, use the prefix from step 2 and add “yne”.  8. Regents trick question: If there is more than one multi-bond, but the appropriate prefix in front of the “ene” or the “yne”.

4.  9. Number the longest continuous chain of carbons starting with 1 so that the branch or functional group is bonded to the lowest possible numbered carbon.  10. If it is just a hydrocarbon branch, go to the next slide, step 11. If it is a functional group on table R, skip the next slide and go to step 15

5.  11. count the number of hydrocarbons on the branch.  12. Use the prefix from table P, add “yl”  13. Put the number of the carbon the branch is on first, the a dach (-)  14. list the branch name, then the name of the base hydrocarbon.

6.  15. Use Table R to determine which functional group you have.

7.  Use the number the carbons where the halogen is bonded  Add the prefix for that halogen to the name of the hydrocarbon.

8.  Use the number the carbon where the –OH is  Change the suffix of the hydrocarbon to “ol”

9.  Count the carbons on each side of the O  Name those with the prefixes from Table P  Add “yl” to those.  If they are both the same use “di”  Put them in from of the word “ether”

10.  Change the suffix of the hydrocarbon to “al”

11.  Use the number which carbon the =O is  Add the suffix “one” to the name of the hydrocarbon

12.  Also called carboxilic acids  Change the suffix from the hydrocarbon to “oic”  Add the word “acid”

13.  Count the carbon chains on either side of the –O-  Add the suffix “yl to the shorter chain.  Name the longer chain with the suffix “oate”

14.  Make sure there is a nitrogen and no oxygen  Count the carbons  Use the prefixes from Table P  Use the suffix “amine”  Don’t worry about the carbon numbers, they never ask that

15.  Name the hydrocarbon chain  Make sure there is both the =O and the N  Use the suffix “amide”
