- A. Aromatic
- B. Dicarboxylic
- C. Hydrocarbons
- D. Fumaric acid
Explanation
Both phthalic acid and oxalic acid share the crucial characteristic of being dicarboxylic acids. This means each molecule possesses two carboxylic acid groups (-COOH) within their structure. Here's a breakdown:Phthalic acid: This aromatic compound features two carboxylic acid groups attached to adjacent carbons on a benzene ring. Its structure depicts the arrangement of these functionalities.Oxalic acid: This aliphatic acid has two carboxylic acid groups linked directly to each other

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.
