1. Hydrocarbons

2. Organic Chemistry Carbon compounds (usually C+H+?) If all were removed from earth? –Look like moon with water If all were removed from our bodies? 9 of 10 million known compounds are organic Used to be compounds from living organisms Organic vs inorganic

3. Why so many organic Compounds? Carbon is so very versatile Carbon chains – 2 to thousands Isomers – same formula – different structure

4. Isomers

6. Functional Groups O, S N, P F, Cl, Br, I Metals

7. Hydrocarbons C and H only – Fossil Fuels Alkanes C-C only (no double or triple) –C n H 2n+2 –Saturated (with H) –Homologous series - +CH 2 –Shapes from models – experiment 5 –Names – IUPAC (not the syrup you take to throw up)

9. Structures

10. Shorthand

11. Find the Isomers of n-pentane Just use carbon skeleton initially Start with straight chain Then remove one carbon and replace it elsewhere Remove two carbons, etc.

12. Hydrocarbons If contain double bonds – alkenes Double bonds must be between? Also called “unsaturated”. With what? Which hydrocarbons are saturated? General formula of C n H 2n Examples: –Ethene (or ethylene) C 2 –Propene (or propylene) C 3 In name, you must tell where double bond is. Shapes from models

14. Alkynes Carbon-carbon triple bonds Most common is ethyne (acetylene) General formula C n H 2n-2

15. Multiple Covalent Bonds

16. Cyclic Hydrocarbons Cycloalkanes: Unsaturated Shorthand

17. Cyclic Hydrocarbons Cycloalkenes:

18. Cyclic Hydrocarbons Aromatics: –Aroma –Contain or built on benzene C 6 H 6 –Many are carcinogenic

20. H10 – C4 4, 5, 7 - 13, 42, 45, 46, 47, 49, 50, 56 - 59, 61, 62 Name isomers
