Carboxylic Acid Derivatives Chapter 14 1 Carboxylic acids The carboxyl group consists of carbonyl and hydroxyl groups attached to the same carbon carb onyl hydr oxyl carboxyl An . Starter:. Use molecular models to make various alcohol molecules. Keywords:. Esterification, elimination, ester, dehydration. Learning Objectives. A. Model the esterification of alcohols with carboxylic acids. 2. 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.. 20-1. Carboxylic acid derivatives undergo substitution reactions via the (often acid- or base-catalyzed) addition-elimination sequence:. The relative reactivities of the substrates follow a consistent order:. 19-4. Carboxylic acids are relatively strong acids.. Carboxylic acids have much lower pK. a. values than do alcohols.. The lowered pK. a. values are due to the electron-withdrawing effect of the positively polarized carbonyl carbon and the resonance stabilization of the carboxylate group.. Upon heating, a slower but thermodynamically more favorable reaction between the carboxylic acid and the amine takes place.. Dicarboxylic acids react with amines to give imides.. Imides, or the nitrogen analogs of cyclic anhydrides, can be formed through the reaction of a dicarboxylic acid and ammonia or a primary amine.. And. Their Derivatives. Chem. 108. Chapter . 10. 1.
