🤓 Based on our data, we think this question is relevant for Professor Falcao's class at UM.
We’re being asked to determine the stereochemical configuration of the following molecules.
Recall that the R/S configuration gives us the absolute stereochemistry of chiral centers. It involves:
Step 1: Determine the priority of groups at the chiral center.
• Priority is determined using atomic mass.
• If the same atom is present, we compare the other atoms it is bonded to.
– Double and triple bonds count twice/thrice.
Step 2: Determine the R/S configuration of the chiral center.
• If the lowest priority is on a dashed line: trace a path from 1 to 3
– If the order is clockwise → R (rectus or right)
– If the order is counterclockwise → S (sinister or left)
• If the lowest priority is not on a dashed line: swap with the group on a dashed line
– Trace a path from 1 to 3:
– Clockwise → R becomes S because of the swap
– Counterclockwise → S becomes R because of the swap
Indicate the stereochemical configuration for the tetrahedral centers shown below.
