Transcribed Image Text:**Educational Website Content: Reaction Completion Using Reagents**
**Objective:** Choose the best reagents to complete the reaction depicted below.
**Reaction Overview:**
The schematic shows an organic compound transformation. The initial structure consists of a hydrocarbon with two triple bonds, transforming into a hydrocarbon with a single bond between carbon atoms in the final structure.
**Reagent Options:**
- **A.** \( \text{H}_2(\text{g}) \) / Pt
- Hydrogen gas in the presence of a platinum catalyst.
- **B.** \( \text{H}_2(\text{g}) \) / Lindlar's catalyst
- Hydrogen gas with Lindlar’s catalyst, used for partial hydrogenation to convert alkynes to cis-alkenes.
- **C.** \( \text{H}_2(\text{g}) \)
- Hydrogen gas, potentially indicating a general hydrogenation process.
- **D.** Na / \( \text{NH}_3(\text{l}) \)
- A sodium metal and liquid ammonia setup, typically for dissolving metal reductions to convert alkynes to trans-alkenes.
- **E.**
1. \( \text{NaBH}_4 \)
2. \( \text{H}_3\text{O}^+ \)
- Sodium borohydride followed by acid, a common reduction method for carbonyl functionalities.
**Visual Representation:**
- The initial line structure shows a hydrocarbon with multiple triple bonds (depicted with three parallel lines).
- Following the reagent interaction, the final line structure exhibits a hydrocarbon with a singular bond style, indicating complete reduction.
**Task:** Analyze the transformation and choose the appropriate reagent that accomplishes the desired conversion effectively. Consider the nature of each reagent and the extent of hydrogenation required for this chemical reaction.
