The relationship between the two drawings is that they represent diastereomers.
Diastereomers:
Diastereomers are stereoisomers that are not mirror images of each other and are not superimposable. They arise when a molecule has more than one chiral center and differs in configuration at some, but not all, of these chiral centers.
In the context of the drawings, the presence of multiple chiral centers is implied by the different arrangements of substituents around certain carbon atoms.
Distinct Arrangements:
The drawings show different spatial arrangements of substituents around at least one chiral center.
The presence of "Me" (methyl) groups and different functional groups indicates that the molecules are not identical.
Not Mirror Images (Enantiomers):
Since the drawings are not mirror images of each other, they are not enantiomers. Enantiomers are non-superimposable mirror images.
Not Constitutional Isomers:
Constitutional isomers have the same molecular formula but different connectivity of atoms. The drawings do not represent constitutional isomers, as the connectivity of atoms appears to be the same.
Conclusion - Diastereomers:
Given the different spatial arrangements around at least one chiral center and the lack of mirror symmetry, the relationship between the two drawings is best described as diastereomers. Diastereomers share some, but not all, stereocenters and exhibit different configurations at those centers.
