Question

**Figure 13: Reactions**

This figure illustrates two chemical reactions.

1. **First Reaction (Top):**
- **Reactants:**
- Phenylacetylene
- Undergoes reaction with lithium acetylide in the presence of DMSO (Dimethyl sulfoxide) through an SN2 mechanism.
- **Intermediate:**
- Subsequent treatment with HgSO₄, H₂SO₄, and H₂O.
- **Product:**
- A phenyl ketone derivative.

2. **Second Reaction (Bottom):**
- **Reactant:**
- A terminal alkyne with branched alkyl groups at both ends.
- **Product:**
- An internal alkylalkene with a butadiene structure, indicating isomerization or double bond formation.

These reactions demonstrate typical transformations involving substitution, addition of reagents, and rearrangement in organic synthesis.

**Learning Target 15**

**Criteria for satisfactory score**

Reactants, products, and reagents that complete a reaction scheme must be specific compounds, not generic categories. Reagents and structures must be valid Lewis structures.

**Tasks**

Complete the synthetic sequences by drawing products/substrates/reagents in empty spaces in reactions below.

*Note: Please ensure all chemical drawings accurately represent the chemical structure as intended for educational purposes.*
