1. Hydrogen Bonding, Aldehydes and Ketones

2. Multi-alcohols Ethylene glycol Glycerol

3. Multi-alcohols PVA – polyvinylalcohol –Soluble in water –Used in glues –Packaging material for medicines

5. Other alcohols PVA – polyvinylalcohol –Soluble in water –Used in glues –Packaging material for medicines THC – tetrahydrocannibinol –Active ingredient in marijuana –Also has an ether functional group –Matches a similar chemical in the brain

6. Hydrogen Bonding Boiling point increases with size of molecule Butane is a gas at room temperature, but methanol is a liquid –Due to hydrogen bonding O is more electronegative than H O on one molecule to H on O on another Also present in water and other alcohols Reason small alcohols are miscible in water

7. -hydrophilic end -hydrophobic end

9. Aldehydes Functional group is C=O at end of chain Naming: Use HC root and add al instead of ol –Example – ethanal (acetaldehyde) –Or methanal (formaldehyde) Both are toxic and in pollution

10. Aldehydes Some have pleasing taste and smell

14. Aldehydes Some have pleasing taste and smell Also used in perfumes –Must be volatile –Many extracted from flowers –Others synthesized –Chanel No. 5

15. Ketones Functional group is C=O in middle of chain Naming: Use HC root and add “one” instead of ol, or al –Example: propanone (acetone) Common solvent –Or butanone (methyl ethyl ketone or MEK)

16. Ketones Give odors and flavors to some foods –Raspberries –Cloves –Spearmint –Blue cheese

17. Oxidation Products 1° alcohols – Aldehydes – then Acids –Example – wine → vinegar 2° alcohols – Ketones 3° alcohols?

18. H17 – C6 18 - 20, 23, 25, 27, 45 - 47, 59 – 61 Name all isomers
