Question
**Question 7:**

**Determine the Relationship Between Molecules**  
Are the molecules shown below enantiomers, diastereomers, constitutional isomers, or identical?

**Description of the Structures:**

The diagram shows two chemical structures:

1. **Left Structure:**
   - Contains two carbon atoms connected by a single bond.
   - A chlorine (Cl) atom is bonded to the first carbon, depicted with a wedge (indicating it is coming out of the plane towards the observer).
   - A bromine (Br) atom is bonded to the second carbon, depicted with a dashed line (indicating it is going into the plane away from the observer).
   
2. **Right Structure:**
   - Similarly contains two carbon atoms connected by a single bond.
   - A chlorine (Cl) atom is bonded to the first carbon, depicted with a wedge (indicating it is coming out of the plane towards the observer).
   - A bromine (Br) atom is bonded to the second carbon, also depicted with a wedge (indicating it is coming out of the plane towards the observer).

**Analysis:**

- Both structures have the same molecular formula and connectivity, indicating they are not constitutional isomers.
- The two structures are non-superimposable mirror images due to the difference in spatial orientation of the Br atom, making them enantiomers.

**Conclusion:**

The molecules are enantiomers.
