Question
**Title: Synthesis of Ketones and Aldehydes from Alkynes** **Introduction** The goal of the following exercise is to determine which of the presented ketones and aldehydes can be synthesized from an alkyne as the only starting material, achieving a good yield (greater than 50%). **Instructions** Review the four molecular structures below and check all applicable options. **Molecular Structures** 1. **Structure 1** - Molecular Formula: Contains a benzene ring attached to a nitrogen atom, followed by a series of carbon atoms, with another nitrogen-containing ring on the end. - Functional Group: Ketone group (C=O) 2. **Structure 2** - Molecular Formula: Hexanone derivative with an alkyl chain ending in a phenyl (Ph) group. - Functional Group: Ketone group (C=O) 3. **Structure 3** - Molecular Formula: Cyclohexyl group connected to a carbon chain that includes a ketone group and ends in a propyl group. - Functional Group: Ketone group (C=O) 4. **Structure 4** - Molecular Formula: Cyclopropylmethyl ketone derivative, with the aldehyde (CHO) group indicated. - Functional Group: Aldehyde group (CHO) **Task** For each of the structures listed, check the box if you consider that the compound can be synthesized from an alkyne in good yield: - [ ] Structure 1 - [ ] Structure 2 - [ ] Structure 3 - [ ] Structure 4 **Note**: Good yield indicates greater than 50%. **Conclusion** By understanding the transformation capability of alkynes to ketones and aldehydes, you will deepen your knowledge in organic synthesis, particularly in the context of functional group transformations.
