The carbons and oxygens of the carboxylic acid functional group are red. (B) This is the structure of oleic acid, an 18-carbon unsaturated fat. The carbons of the alkene functional group ...

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.

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.
