Carboxylic acids are amoebic acids characterized by the attendance of at atomic one carboxyl group. The accepted blueprint of a carboxylic acerbic is R-COOH, area R is some monovalent anatomic group. A carboxyl accumulation (or carboxy) is a anatomic accumulation consisting of a carbonyl (RR'C=O) and a hydroxyl (R-O-H), which has the blueprint -C(=O)OH, usually accounting as -COOH or -CO2H.
Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the a lot of accepted blazon of amoebic acid. Among the simplest examples are formic acerbic H-COOH, which occurs in ants, and acerb acerbic CH3-COOH, which gives alkali its acerb taste. Acids with two or added carboxyl groups are alleged dicarboxylic, tricarboxylic, etc. The simplest dicarboxylic archetype is oxalic acerbic (COOH)2, which is just two affiliated carboxyls. Mellitic acerbic is an archetype of a hexacarboxylic acid. Other important accustomed examples are citric acerbic (in lemons) and tartaric acerbic (in tamarinds).
Salts and esters of carboxylic acids are alleged carboxylates. When a carboxyl accumulation is deprotonated, its conjugate base, a carboxylate anion is formed. Carboxylate ions are resonance counterbalanced and this added adherence makes carboxylic acids added acerb than alcohols. Carboxylic acids can be apparent as bargain or alkylated forms of the Lewis acerbic carbon dioxide; beneath some affairs they can be decarboxylated to crop carbon dioxide.
