Question

Select the correct reagent/s for carrying out each of the following reactions shown below. Put a letter in each box.

This image provides a visual representation of chemical reactions with specific reagents and their resulting products.

1. **Top Reaction**: 

   - **Reactant**: A terminal alkyne (1-butyne).
   - **Product**: A ketone (butanone).
   - **Reagent Options**: The reagents likely used in this reaction are option B – HgSO₄/H₃O⁺. This indicates an oxymercuration-demercuration process that converts the alkyne to a ketone.

2. **Middle Reaction**:

   - **Reactant**: A phenyl-substituted terminal alkyne (phenylacetylene).
   - **Product**: A conjugated diene (styrene).
   - **Reagent Options**: The conversion suggests the use of option E – Li/NH₃, which typically results in the partial reduction of alkynes to trans-alkenes.

3. **Bottom Reaction**:

   - **Reactant**: A chlorocyclohexane.
   - **Product**: A deuterated cycloalkane (cyclohexane-d).
   - **Reagent Options**: Reagents used here are likely C – 1. Li/pentane, 2. D₂O. This process involves the reduction of the alkyl halide using lithium and the introduction of deuterium through D₂O.

**Reagent Key**:

- **A**: H₃O⁺
- **B**: HgSO₄/H₃O⁺
- **C**: 1. Li/pentane 2. D₂O
- **D**: H₂/Pt
- **E**: Li/NH₃
- **F**: 1. BH₃/THF 2. H₂O₂/OH⁻

These reactions highlight various chemical transformations involving reduction, hydration, and deuteration processes using specific reagents.
