### Predict the Product(s) of Bromination Reaction

When an aromatic compound reacts with bromine (\(Br_2\)) in the presence of iron(III) bromide (\(FeBr_3\)), a bromination reaction occurs.

Here is the reaction and possible products.

#### Reaction:
- **Reactants:** Methoxybenzene, \(Br_2\), \(FeBr_3\)
- **Reaction Condition:** Presence of \(FeBr_3\) catalyst

#### Possible Products:
1. **First Product:**
   - **Structure:** The bromine (Br) is substituted at the ortho position relative to the methoxy group (-OCH3) on the benzene ring.

2. **Second Product:**
   - **Structure:** The bromine (Br) is substituted at the para position relative to the methoxy group (-OCH3) on the benzene ring.

   ![Para-Product](prod2.png)

3. **Third Product:**
   - **Structure:** Both ortho and para substituted products are formed. 
   - A mixture containing both the ortho and para products.

4. **Fourth Product:**
   - **Structure:** The bromine (Br) is substituted at the meta position relative to the methoxy group (-OCH3) on the benzene ring.

### Explanation of Each Structure:

- **Ortho-Product:** The bromine (Br) atom is attached to the second carbon adjacent to the carbon with the methoxy group on the benzene ring.
  
- **Para-Product:** The bromine (Br) atom is attached to the fourth carbon relative to the carbon with the methoxy group on the benzene ring.
  
- **Ortho and Para Product Mixture:** A combination of both ortho and para substituted products indicating multiple substitution sites relative to the methoxy group.
  
- **Meta-Product:** The bromine (Br) atom is attached to the third carbon relative to the carbon with the methoxy group on the benzene ring.

#### Note:
The methoxy group (-OCH3) on the benzene ring is an electron-donating group, activating the benzene ring towards electrophilic substitution. The ortho and para positions are more reactive
