PPT-Aldehyde, Ketone, and Carboxylic acids.

Aldehyde Ketone and Carboxylic acids Functional Groups Reactivity Functional groups play a significant role in increasing organic compound reactivity by controlling the direction of the reactions. 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. 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.. Dr. . Sheppard. CHEM . 2412. Summer 2015.

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. 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..

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..
