1. Naming Organic Compounds

2. What is an organic Compound? A compound consisting of carbon. Most consist only of carbon, oxygen, hydrogen and nitrogen.

3. Organic compounds usually consist of chains of carbon atoms with attached functional groups Chains Alkanes Alkenes Alkynes Cyclo alkanes Cyclo alkenes Cyclo alkynes Functional groups Alcohol Amine Aldehydes, ketones Carboxylic acids Esters

4. Functional Groups

5. Chains are named based on the number of carbon atoms number of carbons Meth1 Eth2 Prop3 But4 Pent5 Hex6 Hept7 Oct8 Non9 Deca10 Examples For six carbons Hexane Hexene Hexyne Cylcohexane Cyclohexene Alkyl functional groups are named with the prefix followed by –yl Example methy-l, ethyl-, propyl-

6. To name alkanes, alkenes or alkynes 1.Find the longest carbon chain in the molecule 2.Number the chain so that the functional groups are on the lowest numbers possible 3.The functional groups are listed in alphabetical order

7. Alkenes and alkenes In alkenes (contains a double bond) –ane is replaced by –ene. In alkynes by –yne. The numbering gives the lowest number for the double or triple bond The number giving the location of the bond is written before the base name
