Transcribed Image Text:### Chemical Reactions Involving Alkynes
#### Reaction 1:
- **Reactant:** An alkyne with the following structure: a triple bond followed by a propyl group.
- **Reagents:**
- Water (H₂O)
- Sulfuric acid (H₂SO₄)
- Mercury(II) sulfate (HgSO₄)
This reaction typically results in the addition of water (hydration) across the triple bond, converting the alkyne into a ketone through an enol intermediate.
#### Reaction 2:
- **Reactants:**
1. An alkyne with the structure `CH₃—C≡C—CH₃`
2. Hydrogen gas (H₂)
- **Catalyst:** Lindlar catalyst
The alkyne undergoes partial hydrogenation in the presence of Lindlar's catalyst to form an alkene (designated as compound A).
- **Subsequent Reaction with Compound A:**
- **Reagents:**
- Methanol (CH₃OH)
- Sulfuric acid (H₂SO₄)
This reaction involves further transformation to produce compound B, typically through an etherification or hydration process.
These reactions illustrate the conversion of alkynes to more functionalized organic compounds, demonstrating important synthetic transformations in organic chemistry.
