**Understanding Electron Flow Using Curved Arrows** In chemical reactions, curved arrows are used to depict the movement of electrons. This particular diagram focuses on illustrating electron flow in reactions involving chlorine and water. Your task is to add these electron-pushing arrows to complete the reaction pathway. Consider bond-breaking and bond-forming steps throughout the process. **Diagram Details:** - **Initial Structure:** The first box has a carbon chain, with two chlorine atoms (•Cl) indicated separately, suggesting the presence of free radical chlorine atoms. There is a prompt stating "Select to Add Arrows." - **Reaction Conditions:** Between the initial compound and the next structures, there’s an arrow labeled with the chemical reactants "Cl₂" and "H₂O", indicating the involvement of chlorine and water in the reaction. - **Intermediate Structure:** The middle structure shows a carbon skeleton now bonded to a chlorine atom, displaying a chlorine radical (•Cl) above. The structure encourages adding curved arrows. - **Final Structure:** The last structure also depicts a modified carbon chain, this time with a hydroxyl group (O-H) attached, and a chloride ion (Cl⁻) indicated. Again, there is a section to "Select to Add Arrows." Your goal is to apply your understanding of mechanistic steps to accurately represent the electron transfer for this chlorination reaction.

**Title:** Electron Flow in Organic Reactions **Introduction:** Curved arrows are essential tools used to illustrate the flow of electrons in organic chemistry. The task involves using the provided starting structure to draw curved electron-pushing arrows for the given reaction or mechanistic steps. It is crucial to account for all bond-breaking and bond-making steps. Additionally, draw any missing organic intermediates or products for this reaction. **Instructions:** - Include all lone pairs in the structures. - Ignore inorganic byproducts, counterions, and solvents. **Diagram Explanation:** 1. **Starting Structure:** - A six-membered ring with a bromine atom attached. - The structure includes lone pairs on the bromine indicating potential reaction sites. 2. **Reaction Steps:** - The reaction begins with the addition of \( Br_2 \), leading to an intermediate. - Curved arrows need to be drawn to indicate electron movement during this step. 3. **Intermediate:** - The intermediate structure is shown, with an indication to add arrows to illustrate further electron flow. 4. **Product Formation:** - Water (\( H_2O \)) is added, leading to further reaction steps. - The second intermediate requires the addition of electron flow arrows. 5. **Final Product:** - The product that results from the complete reaction with \( H_2O \). - Complete the structure by adding the relevant bonds and electron pairs. **Conclusion:** By accurately drawing the curved arrows and noting the movement of electrons, one can predict and understand the formation of intermediates and final products in an organic chemical reaction.
