**Title: Identifying Enantiomers of a Cyclohexane Molecule**

**Question:**
Which structure (or structures) represents (or represent) the enantiomer of the molecule below?

**Diagrams:**

- **Target Molecule Diagram:**
  - The structure is a cyclohexane ring with three substituents:
    - Hydroxyl group (OH) attached with a solid wedge.
    - Methoxy group (OCH₃) attached with a dashed wedge.
    - Bromine atom (Br) attached with a solid wedge.

- **Options:**
  - **Structure I:**
    - Cyclohexane ring with substituents:
      - Hydroxyl group (OH) with solid wedge.
      - Methoxy group (OCH₃) with dashed wedge.
      - Bromine (Br) with a solid wedge.
  
  - **Structure II:**
    - Cyclohexane ring with substituents:
      - Hydroxyl group (OH) with a solid wedge.
      - Methoxy group (OCH₃) with a dashed wedge.
      - Bromine (Br) with a dashed wedge.
  
  - **Structure III:**
    - Cyclohexane ring with substituents:
      - Hydroxyl group (OH) in a wedged bond orientation.
      - Methoxy group (OCH₃) in a dashed bond orientation.
      - Bromine (Br) with a solid bond orientation.
  
  - **Structure IV:**
    - Cyclohexane ring with substituents:
      - Hydroxyl group (OH) with a solid wedge.
      - Methoxy group (OCH₃) with a dashed wedge.
      - Bromine (Br) with a dashed wedge.

**Answer Choices:**
- IV
- I
- III and IV
- III
- II

**Explanation:**
The enantiomers are stereoisomers that are non-superimposable mirror images. The molecule corresponding to an enantiomer will have all chiral centers inverted compared to the given molecule. 

**Correct Answer:**
- Option: **IV**

Expert Solution
Step 1

Definition of enantiomer:

An enantiomer is one of two stereoisomers that are non superimposable mirror images of each other.

For example :

Right and left hand of human beings are mirror image of each other but cannot be superimposed.
