🤓 Based on our data, we think this question is relevant for Professor MacDonald's class at TEXAS.
We’re being asked to name the given structure using IUPAC nomenclature with the correct stereochemistry.
We can see that this is a chiral molecule because:
– there is no plane of symmetry present
– there is a chiral center present
Recall that the R/S configuration gives us the absolute stereochemistry of chiral centers. It involves:
Step 1: Name the structure without R/S configuration.
Step 2: 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 3: 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
Give the IUPAC name, including stereochemistry of the compound below
