Carboxylic acids can undergo reduction reactions. Reduction is the opposite of oxidation. For example, ethanoic acid (CH 3 COOH) can be formed by the oxidation of ethanol as shown below.

THE catalytic effect of small amounts of pyridine in the reaction between thionyl chloride and carboxylic acids is well known; Carré and Libermann 1 have shown further that it is of great ...

A carboxylic acid is one which contains -COOH as its functional group. In comparison to mineral acids, carboxylic acids show some similarities, but also, some important differences.

The normal numbering system, starting with the carboxylic acid, is shown in blue. The carbons and oxygens of the carboxylic acid functional group are red. (B) This is the structure of oleic acid ...
