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 ...

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 most common is to begin numbering the carbons from the carboxylic acid functional group, with that carbon labeled as carbon 1. Following this system, linoleic acid has double bonds at the 9 ...

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.
