About Nomenclature, Structure and Preparation
Carboxylic acids are prepared by oxidising primary alcohols or aldehydes, hydrolysing nitriles, esters and amides, and carbonating suitable organometallic compounds. Their structures, IUPAC naming, resonance stabilisation and acidic character explain why carboxylic acids differ from alcohols and phenols, despite all containing oxygen and hydrogen.
