TAILIEUCHUNG - Ebook Organic chemistry (7th edition): Part 2 - John McMurry

(BQ) Part 2 book "Organic chemistry" has contents: Functional derivatives of carboxylic acids, enolate anions and enamines; benzene and the concept of aromaticity; reactions of benzene and its derivatives; catalytic carbon carbon bond formation; carbohydrates,.and other contents. | 600 CHAPTER 17 Alcohols and Phenols annually in the United States by fermentation of corn barley and sorghum and production is expected to double by 2012. Essentially the entire amount is used to make E85 automobile fuel a blend of 85 ethanol and 15 gasoline. Ethanol for nonbeverage use is obtained by acid-catalyzed hydration of ethylene. Approximately 110 million gallons of ethanol a year is produced in the United States for use as a solvent or as a chemical intermediate in other industrial reactions. H2C CH2 h20 h3po4 250 C CH3CH2OH Phenols occur widely throughout nature and also serve as intermediates in the industrial synthesis of products as diverse as adhesives and antiseptics. Phenol itself is a general disinfectant found in coal tar methyl salicylate is a flavoring agent found in oil of Wintergreen and the urushiols are the allergenic constituents of poison oak and poison ivy. Note that the word phenol is the name both of the specific compound hydroxybenzene and of a class of compounds. Phenol also known as carbolic acid Urushiols R different Cqg alkyl and alkenyl chains WHY THIS CHAPTER Up to this point we ve focused on developing some general ideas of organic reactivity on looking at the chemistry of hydrocarbons and on seeing some of the tools used in structural studies. With that background it s now time to begin a study of the oxygen-containing functional groups that lie at the heart of biological chemistry. We ll look at alcohols in this chapter and then move on to carbonyl compounds in Chapters 19 through 23. Naming Alcohols and Phenols Thomson Click Organic Interactive to use a web-based palette to draw structures of alcohols based on their IUPAC names. Alcohols are classified as primary 1 secondary 2 or tertiary 3 depending on the number of organic groups bonded to the hydroxyl-bearing carbon.
