PPT-Carboxylic Acids and Their Derivatives

Dr SHATHA I AQEEL 108 Chem Learning Objectives Chapter nine introduces carboxylic acids and their derivatives by the end of this chapter the students will know The structure of carboxylic acids. 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.

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 Reactivity. :. Functional groups play a significant role in increasing organic compound reactivity, by controlling the direction of the reactions.. Lecture No.2. Aldehyde, Ketone, and carboxylic acids. List of contents:. Aldehyde, Ketone, and carboxylic acids.. The carbonyl group.. Carbonyl Compounds. . Aldehydes and Ketones.. Biological Significance of Ketone Bodies.. 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.. organic chemistry . (II. ). Second . Year . Students. Assistant Lecturer . _ . Duha. . Adnan . Mahmood. 2021. Organic . Chemistry . II. Chapter 1. Carboxylic . Acids.
