### Reaction Mechanism: Substitution Reaction with NaCl

#### Reaction Overview
This image depicts a substitution reaction where an iodide group on an alkene is replaced by a chloride group from NaCl.

#### Reactants and Products
- **Reactant:** An alkene with an iodine substituent.
- **Reagent:** Sodium chloride (NaCl).
- **Product:** An alkene with a chloride substituent in place of the iodine.

#### Reaction Description
- **Starting Material:** The reactant is an alkene structure where a single iodine atom (I) is attached to the molecule.
- **Reagent Involved:** Sodium chloride (NaCl) is used in the reaction, where the chloride ion will participate in the substitution.
- **Product Formation:** The iodide group is replaced by the chloride ion (Cl), resulting in the formation of a new alkyl chloride product.

#### Mechanism
The reaction proceeds through a typical nucleophilic substitution mechanism:
1. The chloride ion (Cl⁻) from NaCl acts as a nucleophile.
2. The iodine atom leaves the molecule as iodide (I⁻), facilitated by the presence of NaCl.
3. The chloride ion replaces the position previously occupied by iodine, forming the new alkyl chloride product. 

The reaction involves the breaking of the C-I bond and the formation of a C-Cl bond.

This type of reaction exemplifies a common method for interchanging halogen atoms in organic molecules, useful in organic synthesis and modifications.
