PPT-Carboxylic Acids

And Their Derivatives Chem 108 Chapter 10 1 Carboxylic acids are strong organic acids which contain the carboxyl group COOH CO 2 H Carboxylic acids are classified as . 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.

Wöhler (1828) made urea from ammonium cyanate. 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.. Functional groups. Acid and esters. . Formic acid. 14.1 . Karboxylsyrer. Structure. Carboxylic acid groups consist of two very polar functional groups. Carbonyl group. Hydroxyl group. Carboxylic acid groups are very polar. Assistance Lecturer . Amjad. Ahmed . Jumaa. IUPAC names of carboxylic acids . Reactions of the carboxylic acids. Aldehydes and ketones. 1.

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.
