### SN2 Reaction Mechanism

**Overview:**
This diagram illustrates the mechanism of an SN2 reaction. The curved arrows depict the flow of electrons during the reaction process, essential for understanding how the reaction takes place.

**Diagram Explanation:**

- **Reactants:**
  - **Methoxide Ion (CH₃O⁻):** On the left, the methoxide ion is shown with a negative charge and two pairs of lone electrons on the oxygen.
  - **Chlorinated Alkane:** On the right, a chlorinated alkane with the chlorine atom attached is depicted. The carbon atom is bonded to a methyl group (CH₃) and a hydrogen atom, with a wedge used to show stereochemistry.

- **Curved Arrows:**
  - The first arrow extends from one of the lone pairs on the oxygen of the methoxide ion to the carbon atom adjacent to the chlorine atom. This indicates the nucleophilic attack where the methoxide ion donates a pair of electrons to form a bond with the carbon.
  - The second arrow shows the departure of the chloride ion, which is indicated by an arrow moving away from the chlorine-carbon bond, signifying the bond's cleavage.

**Stereochemistry:**
- **Wedge and Dash Notation:**
  - The wedge bond indicates that the CH₃ group is coming out of the plane towards the viewer, while the dash (at the end connected to chlorine) indicates the molecule or atom going behind the plane.

**Solvent:**
- **Tetrahydrofuran (THF):** An inert ether solvent is noted in the diagram, essential for conducting many organic reactions without participating in them directly.

This reaction is an example of nucleophilic substitution, second order (SN2), where the backside attack leads to inversion of stereochemistry at the carbon center.
