How would I go about listing the groups from highest priority to lowest priority, and then determining the absolute configuration of the chirality center?

**Model 2: Absolute Configuration in Fischer Projections**

The absolute configuration (R or S) of a chiral center in a Fischer projection is determined in the same way as in a wedge-dash structure. Recall that horizontal bonds should be pointing towards you, and vertical bonds should be pointing back or away from you.

**Diagram Explanation:**

- The diagram on the left shows a Fischer projection for a chiral molecule with the groups arranged as follows: CH₃ (top), CH₂CH₃ (bottom), H (left), and Br (right).
- The diagram on the right illustrates the equivalent wedge-dash structure, where:
- The bond to CH₃ is shown in the plane of the paper.
- The bond to CH₂CH₃ is represented by a dashed line (pointing away).
- The bond to H is shown as a solid wedge (pointing towards the viewer).
- The bond to Br is in the plane of the paper.

**Note:** The configurations in both representations should be interpreted to assign the absolute configuration (R or S) to the chiral center.

Expert Solution

Step 1

Rules: Chrial center is having four groups. You have to give priority according to according to atomic number. Bromine gets first priority and ethyl gets second priority. methyl gets third priority and hydrogen gets fourth priority.

The order of groups are clockwise, then the configuration is R or the order of groups are anticlock wise, then the configuration is S.

Here Hydrogen (fourth priority group) is present in horizontal line then R configuration will becomne S.
