Question
**Assign the configuration of the chiral center in the structure below as R or S, then redraw the Fischer projection as a perspective drawing.**

- **Fischer Projection:**

  ```
    OH
     |
  H--C--Br
     |
    CH₃
  ```

- **Perspective Drawing:**

  (Provided as an empty square, intended for the student to draw the perspective representation of the chiral molecule based on the Fischer projection.)

**Instructions:**

1. **Chiral Center Identification:**
   - Identify the chiral center in the given Fischer projection. The central carbon atom (C) is bonded to four different groups: OH, Br, H, and CH₃.

2. **Assign Configuration (R or S):**
   - Determine the priority of the groups attached to the chiral center based on atomic number: Br > OH > CH₃ > H.
   - Orient the molecule in such a way that the lowest priority group (H) is positioned away from you.
   - Trace the direction of priority from 1 to 3:
     - If the path is clockwise, the configuration is R.
     - If the path is counterclockwise, the configuration is S.

3. **Redraw as a Perspective Drawing:**
   - Draw the carbon atom as a wedge-and-dash representation, showing the three-dimensional orientation.
   - Use wedge lines to represent bonds coming out of the plane and dashed lines for bonds going behind the plane.

**Note:** This exercise enhances understanding of stereochemistry by translating two-dimensional Fischer projections into three-dimensional perspective drawings.
