### Chemical Reaction: Substitution on a Cyclopentane Ring

**Molecular Structure:**
- **Reactant:** A cyclopentane ring with a bromine atom (Br) attached to one of the carbon atoms.

**Reaction Conditions:**
- **Reagents:** Sodium cyanide (NaCN) and hydrogen cyanide (HCN).

**Reaction Type:**
- This image depicts a nucleophilic substitution reaction where the bromine atom on the cyclopentane ring is replaced by a cyano group (CN).

**Explanation:**
- The bromine atom is a good leaving group, and in the presence of NaCN, the cyanide ion (CN⁻) serves as a nucleophile. 
- The cyanide ions will attack the carbon atom bonded to the bromine, leading to the substitution of the bromine by a cyano group, resulting in the formation of a nitrile group on the ring.

**Significance:**
- This type of reaction is useful for introducing a nitrile functional group into an organic molecule, which can then be further transformed into other functional groups such as carboxylic acids or amines through subsequent reactions.
