**Exercise 4: SN2 Reaction Mechanism**

**Objective:**
Provide the mechanism with curved arrows and identify the products for the following SN2 reaction.

**Reaction Components:**
- Reactant 1: A benzyl group attached to an oxygen-sulfur trifluoromethyl group (O-SO2-CF3).
- Reactant 2: A negatively charged methoxy group (CH3O⁻).

**Instructions:**
1. Illustrate the mechanism using curved arrows to indicate electron movement.
2. Identify the final products of the reaction.

**Concepts:**
- **SN2 Reaction (Substitution Nucleophilic Bimolecular):** 
  - A type of nucleophilic substitution where the nucleophile attacks the electrophile, resulting in the displacement of a leaving group.
  - The reaction proceeds via a single transition state, implying a concerted mechanism.

**Diagram Explanation:**
- **Curved Arrows:** 
  - Show electron flow from the methoxy group's lone pair to the electrophilic carbon.
  - Indicate the leaving group (O-SO2CF3) being displaced at the same time.
  
Understanding and accurately depicting the SN2 mechanism with curved arrows is crucial in predicting the reaction outcome and identifying the products formed.
