Question

Please explain the mechanism. 

The image depicts a chemical reaction involving an organic compound and reagents. 

### Reactant:
- **Structure**: The structure shown is an alkene with a double bond and a cyclopentane ring.
- **Compound Type**: An alkene with a substituted cyclopentane ring.

### Reagents and Conditions:
- **Reagents**: 
  - **HBr (Hydrobromic Acid)**: A source of bromine ions, commonly used in addition reactions with alkenes.
  - **ROOR (Organic Peroxide)**: Often used as a radical initiator in reactions.

### Reaction:
- **Description**: 
  - This reaction represents a radical addition mechanism known as the anti-Markovnikov addition of HBr in the presence of a peroxide (ROOR).
  - The presence of peroxide changes the typical Markovnikov addition to an anti-Markovnikov addition, where the bromine atom adds to the less substituted carbon in the alkene.

This setup is used to illustrate the mechanism of radical halogenation, showing the exception to the general rule in hydrohalogenation of alkenes.
