![The reaction below shows a Claisen condensation.
**Reaction:**
\[ 2 \, \text{CH}_3\text{COEt} \quad \overset{1. \, \text{EtO}^{-}\text{Na}^+}{\longrightarrow} \overset{2. \, \text{H}_2\text{O, HCl}}{\longrightarrow} \quad \text{CH}_3\text{CCH}_2\text{COEt} + \text{EtOH} \]
- **Ethyl ethanoate (ethyl acetate):** \( \text{CH}_3\text{COEt} \)
- **Ethyl 3-oxobutanoate (Ethyl acetoacetate):** \( \text{CH}_3\text{CCH}_2\text{COEt} \)
- **Ethanol:** \( \text{EtOH} \)
**Mechanism:**
Draw curved arrows to show the movement of electrons in the step of the mechanism shown below.
**Diagram Description:**
- The diagram features an arrow-pushing instruction visual, illustrating electron movement.
- The first structure shows \( \text{CH}_3\text{COEt} + \text{CH}_2\text{COEt} \).
- A curved arrow is drawn from the alpha carbon hydrogen of the first molecule to the oxygen of the carbonyl, indicating deprotonation.
- This results in a resonance-stabilized tetrahedral intermediate:
- In the intermediate, the deprotonated form (\( \text{C}^- \)) of the alpha carbon is shown forming a bond with the carbonyl carbon of the second molecule, resulting in a negative charge on the oxygen.
- The structure displays a formation of \( \text{CH}_3\text{C}^- \text{CH}_2\text{COEt} \).
**Note:** This intermediate is referred to as a "tetrahedral carbonyl addition intermediate."](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdf8f923a-fead-432c-9268-8665df60689d%2F8758558f-b6b9-4fc0-9cc8-9d5592334c99%2F8bqqptf_processed.png&w=3840&q=75)
