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.

carboxaldehydes can participate in condensations with primary amines to form enamines and carboxylic acids can undergo decarboxylations, resulting in loss of carbon dioxide. Nature's redox enzymes ...
