WHAT DOES CARBOXYL GROUP MEAN IN ENGLISH?
A carboxylic acid /ˌkɑrbɒkˈsɪlɪk/ is an organic compound that contains a carboxyl group (C(O)OH). The general formula of a carboxylic acid is R-C(O)OH with R referring to the rest of the (possibly quite large) molecule. Carboxylic acids occur widely, and include the amino acids and acetic acid (active ingredient in vinegar). Salts and esters of carboxylic acids are called carboxylates. When a carboxyl group is deprotonated, its conjugate base forms a carboxylate anion. Carboxylate ions are resonance stabilized and this increased stability makes carboxylic acids more acidic than alcohols. Carboxylic acids can be seen as reduced or alkylated forms of the Lewis acid carbon dioxide; under some circumstances they can be decarboxylated to yield carbon dioxide.
