The IUPAC name of Malonic acid CH2(COOH)2 is
Correct answer: B. 1,3-Propanedioic acid
- A. 1,2-Ethanedioic acid
- B. 1,3-Propanedioic acid
- C. 1,4-Butanedioic acid
- D. 1,6-Hexadecanoic acid
Explanation
The correct IUPAC name for Malonic acid is 1,3-Propanedioic acid. Malonic acid consists of a three-carbon chain with two carboxyl groups attached at the first and third positions. Option A, 1,2-Ethanedioic acid, refers to oxalic acid, which has only two carbon atoms. Option C, 1,4-Butanedioic acid, describes a compound with a four-carbon chain, which does not match malonic acid's structure. Option D, 1,6-Hexadecanoic acid, is completely unrelated as it refers to a much larger molecule with a sixteen-carbon backbone.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
