1. Stereochemistry

2. Stereochemistry
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

7. Asymmetric Compounds
Compounds with no plane of symmetry

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

9. All completely symmetric compounds are non-polar

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

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

12. Hydrocarbons are non-polar
Polarity of Hydrocarbons
Hydrocarbons are non-polar

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

14. A carbon center must be bound to 4 different things to be asymmetric
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. Movement down an energy gradient
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
