Question
**Title: Understanding the Flow of Electrons in Chemical Reactions**

**Introduction to Curved Arrow Notation:**

Curved arrows are a crucial tool in organic chemistry, used to represent the flow of electrons during chemical reactions. This notation helps visualize how bonds are broken and formed, which is essential for predicting reaction products.

**Exercise: Electron Flow in Aromatic Compounds**

**Instructions:**

Follow the curved arrows and draw the products of the given reaction. Ensure all lone pairs and charges are included in your drawing. Inorganic byproducts can be ignored for this exercise.

**Reaction Details:**

1. **Starting Material**: A benzene ring with a fluorine substituent and a negatively charged potassium cation (\( K^+ \)) situated above the molecule.
2. **Curved Arrows**: There are arrows indicating:
   - Movement of electrons from a lone pair on the negatively charged oxygen (part of a hydroxyl group) towards the hydrogen atom.
   - Another arrow from the bond between hydrogen and its adjacent atom.
   
**Objective:**

Accurately depict the resulting organic compound and the rearrangement of electrons as indicated. Use the space below to draw your response.

**Diagram Summary:**

- **Benzene Ring**: Enhances resonance and stability.
- **Fluorine Substituent**: Affects electron distribution due to its electronegativity.
- **Curved Arrows**: Guide the transition state by highlighting electron shifts.

By completing this exercise, you will improve your understanding of electron movements and prediction of chemical reaction outcomes.

**Note**: Use the "Select to Draw" area to input your drawing of the reaction products.

**Conclusion:**

Mastering curved arrow notation is vital for understanding and predicting the behavior of molecules in organic chemistry. Practice regularly to build proficiency in electron flow analysis.
