Question
**Question:** Which compound is the major product of the reaction sequence shown?

**Reaction Sequence:**

1. Starting material: A carboxylic acid with a propane chain.

2. Reagents:
   - \( \text{(1) SOCl}_2 \)
   - \( \text{(2) (CH}_3)_3\text{CO}\, \overset{\oplus}{\underset{\ominus}{\text{Na}}} \)
   - \( \text{(CH}_3)_3\text{COH} \)

**Possible Products:**

- **Compound A:** Propanoic acid.
- **Compound B:** Sodium propionate.
- **Compound C:** Propanoyl chloride.
- **Compound D:** Sodium tert-butoxide.

**Options:**

- \( \bigcirc \) Compound D
- \( \bigcirc \) Compound A
- \( \bigcirc \) Compound C
- \( \bigcirc \) Compound B

**Explanation:**

This problem asks to determine which compound is the main product after a carboxylic acid reacts through a sequence involving thionyl chloride (\( \text{SOCl}_2 \)) and sodium tert-butoxide.

1. **Reaction with \( \text{SOCl}_2 \):** The carboxylic acid is converted to an acyl chloride.
2. **Reaction with Sodium tert-butoxide:** Generally forms an ester, indicating the role of sodium tert-butoxide as a base.

Consider each proposed compound as a possible outcome of the illustrated reaction sequence.
