  1. Chapter 10 Part A - Reactions of Alcohols Ethers – Not Included Amines – In a separate Chapter

  2. Alcohols Alcohols contain a hydroxy group (OH) bonded to an sp3 hybridized carbon.

  3. Nomenclature of Alcohols

  4. 2,3-dimethyl-cyclohexanol 4-methyl-cyclopent-2-enol 3-ethyl-5-methyl-cyclohexanol Nomenclature of Alcohols

  5. Give IUPAC names for the following compounds.

  6. Preparation of Alcohols • Alcohols are common products of nucleophilic substitution. What are other methods of preparing alcohols?

  7. Reactions of Alcohols - Dehydration • Dehydration is a eliminationreaction.

  8. Examples of Dehydration

  9. Conversion of Alcohols to Alkyl Halides with HX The reaction of alcohols with HX (X = Cl, Br, I) is a general method to prepare 1°, 2°, and 3° alkyl halides.

  10. Oxidation of Alcohols Can be accomplished by inorganic reagents, such as KMnO4, CrO3, and Na2Cr2O7 or by more selective, expensive reagents

  11. Oxidation of Primary Alcohols • To aldehyde: pyridiniumchlorochromate (PCC, C5H6NCrO3Cl) in dichloromethane • Other reagents produce carboxylic acids

  12. Oxidation of Secondary Alcohols

  13. Identify the alcohols can be used as the starting materials to form each of the following carbonyl compounds?
