Question
### Completing a Proton-Transfer Reaction

In this exercise, you'll complete the equation for the given proton-transfer reaction by using curved arrows to show the flow of electron pairs and drawing the products. Follow these steps:

- **Draw all atoms**, including hydrogen atoms.
- **Apply formal charges** where appropriate.
- **Assign lone pairs** and radical electrons where necessary.
- Use the **"starting points" menu** to revert to the original molecule(s) shown.
- **Draw the appropriate electron-flow arrows**.
- **Omit '+' signs** between structures.

#### Diagram Explanation:
- **Reactants:**
  - On the left, there is an ethoxide ion (\( \text{C}_2\text{H}_5\text{O}^- \)) with a negatively charged oxygen atom showing three lone pairs. 
  - On the right is a hydrogen chloride molecule (\( \text{HCl} \)) with three lone pairs on the chlorine atom.

- **Curved Arrows:**
  - A curved arrow originates from the lone pair on the oxygen atom, pointing towards the hydrogen atom of \( \text{HCl} \).

- **Products:**
  - The diagram's right side is currently blank, indicating that you need to draw the resulting molecules of the proton transfer.

#### Note
The use of ChemDoodle is referenced for drawing the molecules and reactions.

This representation helps in visualizing the flow of electrons during a proton-transfer reaction and understanding the concept of acid-base chemistry and electron movement in organic reactions.
