Chemistry - Carboxylic acid and their Derivatives Question with Solution | TestHub

Question Explanation:

The question asks to match the reactions in Column (I) with the products in Column (II) .

Concept:

This problem is based on the effect of heating on carboxylic acids , particularly dicarboxylic acids .

Solution:

Geminal dicarboxylic acids (two –COOH groups on the same carbon) are unstable and, on heating, decarboxylate to evolve CO₂ .

Vicinal dicarboxylic acids (–COOH groups on adjacent carbons) undergo dehydration on heating , eliminating a water molecule to form cyclic anhydrides .
