PPT-Chapter 14: Carboxylic Acids

2 Introduction The functional group of carboxylic acids consists of a CO with OH bonded to the same carbon Carboxyl group is usually written COOH Aliphatic acids have an alkyl group bonded to COOH. Aldehydes. The term Aldehyde come for the words . al. cohol . dehy. drogenation. . Preparation: Oxidation of primary alcohols according to the following equation:. Note: Oxidation can be considered as removal of hydrogens. Dr. . Sheppard. CHEM . 2412. Summer 2015.

In this chapter, we study carboxylic acids, another class of organic compounds containing the carbonyl group.. The functional group of a carboxylic acid is a . carboxyl group. Alcohols. Ethanol. Ethanol is produced from the fermentation of glucose. Glucose is often derived from the hydrolysis of more complex carbohydrates. (C. 6. H. 10. O. 5. ). n. + nH. 2. O . . nC. 6. 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.

Chapter nine introduces carboxylic acids and their derivatives. . by the end of this chapter the students . will . know :. The structure of carboxylic acids. Ch. 11.4. Combustion of alcohols . Alcohols undergo complete combustion to form carbon dioxide and water.. Denatured alcohol is a useful portable fuel (e.g. for camping stoves) as, unlike LPG, it does not need to be transported in heavy, specialized containers. It is also used as a solvent.. Proteins.
