Show the mechanisms of the reactions below
Transcribed Image Text:The image displays a chemical reaction mechanism involving two compounds:
1. **Reactant**: A cyclopentanone with an alcohol group (hydroxyl group, OH) attached. The structure features a five-membered ring with a ketone group (C=O) adjacent to an OH group.
2. **Reagents**:
- Step 1: NaNH₂ (Sodium amide)
- Step 2: H⁺ (Proton source, typically an acid)
3. **Product**: The product is an alkyne, specifically a terminal alkyne with the structure depicted as a triple bond (C≡C) at the end of a straight chain.
**Reaction Explanation**:
- The reaction involves the conversion of a ketone-alcohol compound into an alkyne.
- In the first step, the cyclopentanone reacts with sodium amide (NaNH₂), which likely acts as a strong base to deprotonate the hydroxyl group, facilitating elimination.
- In the second step, the introduction of a proton (H⁺) might assist in stabilizing the resulting structure or completing the elimination process, leading to the formation of the alkyne.
This reaction illustrates a typical transformation in organic chemistry where a ketone is converted to an alkyne through the use of a strong base and acid in subsequent steps.
