On the left side:

- **Instruction:** "Draw the starting structure that would lead to this major product (and its enantiomer) under these conditions."

- **Reaction Description:** Br\(_2\) is added to an empty rectangle that indicates the need for a starting structure. The product shown is a chain with two bromine atoms added across what would typically be a double bond, indicating a dibromination. The bromine atoms are shown with wedge and dash bonds, signifying stereochemistry and possibly leading to enantiomers.

On the right side:

- **Instruction:** "Draw the product of this reaction. Ignore inorganic byproducts."

- **Starting Structure:** A chain featuring a double bond, likely 1-hexene or similar alkene, is present before the reaction.

- **Reaction Description:** Cl\(_2\) is added to the alkene, indicating a halogenation reaction resulting in the addition of chlorine across the double bond. The exact product structure is not provided but would likely include two chlorine atoms added across the double bond site, with attention to potential stereochemistry.

**Diagram Explanation:**

**Left Reaction:**
1. **Starting Material:**
   - **Structure:** A six-carbon hydrocarbon with a double bond (alkene).
   - **Configuration:** The molecule is 3-methylpent-2-ene.

2. **Reagent:**
   - **Br₂ (Bromine):** Used as the halogenation agent.

3. **Process:**
   - **Indication:** A downward arrow indicates the progression of the reaction.

**Right Reaction:**
1. **Starting Material:**
   - **Structure:** A cyclohexene ring.
   - **Configuration:** A simple six-membered cyclic alkene.

2. **Reagent:**
   - **Cl₂ (Chlorine):** Used as the halogenation agent.

3. **Process:**
   - **Indication:** A downward arrow signifies the course of the reaction.

**Objective:**

- **Task:** For each reaction, draw one enantiomer of the major product.
- **Details:** Use wedge and dash bonds to show the 3D arrangement of atoms where stereochemistry is relevant.
- **Note:** Inorganic byproducts are not considered in the final structures.

**Key Learning Points:**

- Understanding the reaction mechanisms of alkenes with halogens.
- Mastering the use of stereochemistry in chemical structures.
- Identifying major products and their enantiomers in halogen addition reactions. 

This exercise will enhance your comprehension of organic reactions and the visualization of molecular geometry.
