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
