The IUPAC or common systematic name assigned to propane-1,3-dioic acid is_________________?
Show answer Hide answer
Answer: C. Malonic acid
Explanation
Malonic acid is the widely accepted common name for propane-1,3-dioic acid. The systematic IUPAC name reflects a three-carbon chain with carboxylic acid groups. Both naming conventions describe the exact same dicarboxylic acid chemical structure. Dicarboxylic acids contain two carboxylic acid functional groups located within the same molecule. Propane-1,3-dioic acid features a central methylene carbon flanked by two carboxyl groups. Organic nomenclature rules provide systematic ways to name complex carbon chain structures.
Malonic acid serves as an important intermediate in various organic syntheses and biochemical pathways. Derivatives of malonic acid are frequently used to synthesize barbiturates and complex vitamins. Understanding dicarboxylic acids helps explain acidity trends in organic molecular structures. Oxalic acid is the common name for the simpler two-carbon ethane-1,2-dioic acid. Aromatic acid is a general class descriptor rather than a specific systematic chemical name. Fumaric acid represents the trans isomer of unsaturated four-carbon butenedioic acid.
