Exercise 17-4: Reactions of Alcohols Outcomes: After completing this activity, you should be able to 1. Provide products for the oxidation of alcohols or reagents for formation of aldehydes (ketones) or carboxylic acids. 2. Provide products and a mechanism for the conversion of alcohols to alkyl halides using PBror SOCI. 3. Provide products and a mechanism for the conversion of alcohols to alkyl halides using HX 4. Provide products and a mechanism for the dehydration of alcohols under acidie (H,0%) or basic (POCl/pyridine) conditions. 5. Explain the formation and reactions of alkoxides and phenoxides. Activity Complete the summary sheet on the reactions of alcohols. Conversion Description Examples Alcohols to Halides Alcohols to Alkenes Alcohols to Aldehydes, Ketones, or Carboxylic Acids Alcohols to Ethers Critical Thinking Questions 1.
