### Reaction Description:

This image illustrates a nucleophilic substitution reaction involving an alkyl chloride and sodium cyanide in acetone at 25°C.

#### Reactants:
- **2-Chlorobutane**: The organic compound depicted on the left side is 2-chlorobutane, which is an alkyl chloride. The chlorine atom is attached to the second carbon of a butane chain.
- **Sodium Cyanide (Na⁺ ⁻C≡N):** The reagent shown is sodium cyanide. It consists of a sodium ion (Na⁺) and a cyanide ion (⁻C≡N), where the carbon and nitrogen atoms are triple bonded.

#### Solvent and Conditions:
- **Acetone:** The reaction is carried out in acetone, a polar aprotic solvent, which helps facilitate the substitution reaction.
- **Temperature:** The reaction occurs at 25°C.

### Reaction Mechanism:
The nucleophilic cyanide ion (⁻C≡N) attacks the electrophilic carbon atom that is bonded to the chlorine atom in 2-chlorobutane. This leads to the displacement of the chloride ion (Cl⁻) and the formation of a carbon-carbon bond between the butane chain and the cyanide ion.

### Result:
This reaction results in the formation of a nitrile compound, where the cyanide group replaces the chlorine atom in the original alkyl chloride.
