Problem: Write IUPAC names for the following compounds:

FREE Expert Solution

We’re being asked to name the given structure using IUPAC nomenclature.



Numbering from clockwise gives us:


 To 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
