Solution

Solution Steps

Step 1: Identify the asymmetric carbons

In each Fischer projection, identify the carbon atoms that are bonded to four different groups, making them chiral centers.

Step 2: Assign priorities to the substituents

For each chiral center, assign priorities (1 to 4) to the substituents based on atomic number, with 1 being the highest priority and 4 the lowest.

Step 3: Determine the configuration (R or S)

Orient the molecule so that the substituent with the lowest priority (4) is pointing away from you.
Determine the order of the remaining three substituents (1 to 3). If the order is clockwise, the configuration is R. If counterclockwise, the configuration is S.
