2. Alcohols, Ethers and Thiols

3. Alcohol Classification

4. Alcohol Nomenclature
Select the longest carbon chain connected to the OH group
Change the suffix from e to ol

5. Alcohol Nomenclature
Select the longest carbon chain containing the OH group
Change the suffix from e to ol
Number the chain with OH group having priority

6. For cyclics the carbon with OH is #1
Alcohol Nomenclature
For cyclics the carbon with OH is #1

7. Alcohol Nomenclature

8. Name groups and then add ether
Ether Nomenclature
Name groups and then add ether

9. Common names of cyclic ethers
Ether Nomenclature
Common names of cyclic ethers

10. Thiol Nomenclature
Name similar to alcohols
Retain the e and add thiol

11. higher number of carbon atoms bonded when finished
Zaitsev’s Rule
higher number of carbon atoms bonded when finished

12. Higher degree – Easier Dehydration

13. Oxidation of primary alcohols

14. Oxidation of secondary alcohols

15. Reactions of Ethers
Ethers tend to have low reactivity. They make good solvents for other reactions to take place in. This is due to good solvent properties such as being partially polar.

16. Oxidation of Thiols

17. Hydrogen Bonding Must have a H connected to a F,O or N
Alcohols can hydrogen bond so their boiling and meting points are higher than corresponding hydrocarbons

18. Ethers or Thiols cannot H Bond
Why????

19. Solubility
The ability to be solvated increases with hydrogen bonding ability
Alcohols > Ethers > Hydrocarbons
