The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
In organic chemistry, a carboxylic acid is an organic acid that contains a carboxyl group (−C(=O)−OH) [1] attached to an R-group. The general formula of a carboxylic acid is often written as R−COOH or R−CO 2 H, sometimes as R−C(O)OH with R referring to an organyl group (e.g., alkyl, alkenyl, aryl), or hydrogen, or other groups ...

As for monofunctional carboxylic acids, derivatives of the same types exist; [clarification needed] however, there is the added complication that one or both of the carboxylic groups could be altered. [citation needed] If only one is changed then the derivative is termed "acid", and if both ends are altered it is called "normal".
According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides), but not according to the IUPAC. [ 1 ] An example of an ester formation is the substitution reaction between a carboxylic acid ( R−C(=O)−OH ) and an alcohol (R'OH), forming an ester ( R−C(=O)−O−R' ), where R and R′ are ...
Other organic carbonyls are urea and the carbamates, the derivatives of acyl chlorides chloroformates and phosgene, carbonate esters, thioesters, lactones, lactams, hydroxamates, and isocyanates. Examples of inorganic carbonyl compounds are carbon dioxide and carbonyl sulfide. [citation needed]
Propionic acid displays the general properties of carboxylic acids: it can form amide, ester, anhydride, and chloride derivatives. It undergoes the Hell–Volhard–Zelinsky reaction that involves α-halogenation of a carboxylic acid with bromine, catalysed by phosphorus tribromide, in this case to form 2-bromopropanoic acid, CH 3 CHBrCOOH.

Carboxylic acids attached to a benzene ring are structural analogs of benzoic acid (Ph−COOH) and are named as one of its derivatives. Citric acid. If there are multiple carboxyl groups on the same parent chain, multiplying prefixes are used: Malonic acid, CH 2 (COOH) 2, is systematically named propanedioic acid. Alternatively, the suffix ...
