Chemistry · Carboxylic Acids: Acidic strength and factors affecting it
Which one of the following acids undergoes decarboxylation on strong heating: Th
Which one of the following acids undergoes decarboxylation on strong heating: This question has multiple correct options
- A. Adipic acid
- B. 3 - butenoic acid
- C. Formic acid
- D. Salicylic acid
Step-by-step solution
Salicylic acid (o-hydroxybenzoic acid) undergoes decarboxylation upon strong heating to produce phenol and carbon dioxide due to the presence of the ortho hydroxyl group that stabilizes the transition state. In contrast, formic acid decomposes to CO and H2O, not decarboxylation. Adipic acid and 3-butenoic acid also decarboxylate but require specific conditions; however, salicylic acid is the most classic example.
