1. Stereochemistry

2. Any chemistry which involves orientation in space

3. Symmetry Referring to anything that can be divided on some plane into identical parts

4. Symmetry In molecules, planes of symmetry can be determined along any bond axis

5. Symmetric Compounds Compounds with at least one plane of symmetry

6. Name the Following C C C C-C-C-C-C-C-C C-C

7. Asymmetric Compounds Compounds with no plane of symmetry

8. Symmetric Compounds The mirror images of symmetric compounds are identical

9. Symmetric Compounds All completely symmetric compounds are non-polar

10. Asymmetric Compounds The mirror images of asymmetric compounds are not identical. They are optical isomers

11. Asymmetric Compounds Asymmetric compounds can be polar if the bonds are polar

12. Polarity of Hydrocarbons Hydrocarbons are non-polar

13. Optical Isomers Mirror images of asymmetric compounds are optical isomers or stereoisomers

14. Stereoisomerism of C A carbon center must be bound to 4 different things to be asymmetric

15. Stereoisomerism of C Any carbon center bound to 3 or less things has at least one plane of symmetry

16. Stereoisomerism of C Use modeling

17. Stereoisomerism of Carbon Chains The constituents on two adjacent carbons spend more time in the staggered position

18. Stereoisomerism of Carbon Chains Use modeling to show aligned & staggered positions

19. Diffusion Movement down an energy gradient

20. Thermochemistry Compounds will eventually move to the lowest possible energy state (the most stable state)

21. Thermochemistry of Organic Compounds Stability is sometimes determined by how the compound interferes with its surroundings

22. Thermochemistry of Organic Compounds To increase stability, organic compounds tend to curl up

23. Thermochemistry of Organic Compounds Organic compounds ring structures are more stable than their corresponding straight chain structures
