  1. Naming Organic Compounds If you don’t know how to name organic compounds, they will really knock you down on the test!

  2. IUPAC System International Union of Pure and Applied Chemistry System used to name organic compounds

  3. Naming Hydrocarbons: *Table P  prefix *Table Q  suffix * numbers are used when there are isomers 1-butene 2-butene How else could we write 1-butene?

  4. *For more than one alkyl group: • 2 – di • 3 – tri • 4 - tetra 2,3-dimethylbutane 2,2-dimethylbutane 2,2-dimethylbutane

  5. CH3 • Find the longest Carbon chain • Number from the shortest end C – C – C – C – C – C 3-methyl hexane C – C – C – C – C – 2-methyl pentane CH3

  6. CH3 CH3 C – C – C – C – C – 2,3-dimethyl pentane 3-ethyl hexane C – C – C – C – C – C C C

  7. – C – C – C – C – 2-methyl butane 2,3-dimethyl pentane C C C – C – C – C – C – C

  8. 3-methyl hexane C – C – C – C – C – C C

  9. Alkenes: • Find the longest chain with the double bond • Number to make double bond smallest possible • End in “ene” 4-methyl-1-pentene 1 2 3 4 5

  10. Draw molecular structures: *start with the right part of the name and go left 2-pentyne 2,3-dimethyl hexane

  11. Learning Check: • Draw the molecular structure for: 4-ethyl-2,3,4-trimethyl octane
