Question
Which of the following pairs of compounds are keto-enol tautomers?
The image features three pairs of chemical structures labeled (a), (b), and (c). Each pair includes two structures identified as I and II. **Pair (a):** - Structure I: This is a ketone. The main chain features four carbon atoms, with an OH group connected to the second carbon, showing an enol form. - Structure II: This is an aldehyde with four carbon atoms. The ketone carbonyl group is placed on the second carbon. **Pair (b):** - Structure I: This structure also presents as an enol, similar to (a), consisting of a four-carbon chain with an OH group on the second carbon. - Structure II: Another enol isomer, with the OH group positioned on the double-bonded carbon, but in a different arrangement. **Pair (c):** - Structure I: This is a cyclohexanone with the ketone functional group doubly bonded to an oxygen at one carbon. - Structure II: This structure is an enol form of cyclohexanone, displaying an OH group double-bonded to the second carbon in the ring. These schematic representations exemplify enol and ketone forms across different organic chemical structures.
