**Title:** Understanding the SN2 Reaction Mechanism

**Instructions:**
For the substitution (SN2) reaction below, circle the nucleophile and draw a box around the electrophile. Then, using curved arrows, draw the reaction mechanism.

**Diagram Explanation:**

1. **Reactants:**
- A cyclohexane ring is shown with a bromine atom (Br) attached as a leaving group.
- \( \text{CH}_3\text{S}^- \) (methanethiolate anion) is depicted as the nucleophile.

2. **Reaction Condition:**
- The reaction is indicated to occur in the presence of acetone, a common solvent for SN2 reactions.

3. **Curved Arrow Notation:**
- Curved arrows in organic chemistry illustrate the movement of electron pairs. In an SN2 reaction, a single step process, the nucleophile attacks the electrophile simultaneously as the leaving group departs.

4. **Product:**
- The product of this reaction is a cyclohexane with the methanethiol group \( \text{H}_3\text{S} \) replacing the bromine.

---

In this SN2 reaction, the methanethiolate anion acts as the nucleophile, attacking the electrophilic carbon atom bonded to bromine. Concurrently, bromine leaves, resulting in the substitution product.
