Chapter 20 ? 2010, Prentice Hall Organic Chemistry, 7th Edition L. G. Wade, Jr. Carboxylic Acids Chapter 20 * Introduction The functional group of carboxylic acids consists of a C?O with ?OH bonded to the same carbon. Carboxyl group is usually written ?COOH. Aliphatic acids have an alkyl group bonded to ?COOH. Aromatic acids have an aryl group. Fatty acids are long-chain aliphatic acids. Chapter 20 Chapter 20 * Common Names Many aliphatic acids have historical names. Positions of substituents on the chain are labeled with Greek letters starting at the carbon attached to the carboxylic carbon. Chapter 20 Chapter 20 * IUPAC Names Remove the final -e from alkane name, add the ending -oic acid. The carbon of the carboxyl group is #1. Chapter 20 Chapter 20 * Unsaturated Acids

Chapter 11 Reactions of Alcohols ?2010, Prentice Hall Organic Chemistry, 7th Edition L. G. Wade, Jr. Chapter 11 * Types of Alcohol Reactions Dehydration to alkene Oxidation to aldehyde, ketone Substitution to form alkyl halide Reduction to alkane Esterification Tosylation Williamson synthesis of ether Chapter 11 Chapter 11 * Summary Table Chapter 11 Chapter 11 * Oxidation States Easy for inorganic salts: CrO42- reduced to Cr2O3. KMnO4 reduced to MnO2. Oxidation: Gain of O, O2, or X2; loss of H2. Reduction: Gain of H2 (or H-); loss of O or O2; and loss of X2. The gain or loss of H+, H2O, HX, etc. is neither an oxidation nor a reduction. Chapter 11 Chapter 11 * Oxidation States of Carbons Chapter 11 Chapter 11 *
