Are these enantiomers, diastereomers, or the same compound?

**Question 5.7:** Are these enantiomers, diastereomers, or the same compound?

**Structural Diagrams:**

- **Left Structure:** Displays a cyclohexane ring with one methyl group shown using a solid wedge (indicating it is coming out of the plane) and another methyl group represented by a dashed line, indicating it is going away from the plane.

- **Right Structure:** Displays a cyclohexane ring with two methyl groups both represented by dashed lines, indicating they are both oriented away from the plane.

**Analysis:**

To determine whether these structures are enantiomers, diastereomers, or the same compound, consider their spatial arrangement:

1. **Enantiomers:** Stereoisomers that are non-superimposable mirror images.
2. **Diastereomers:** Stereoisomers that are not mirror images.
3. **Same Compound:** Identical in every aspect including spatial arrangement.

Comparing the spatial arrangement of substituents on the cyclohexane rings will clarify the relationship between these compounds. If the spatial orientations differ in such a way that one compound is the mirror image of the other (yet not superimposable), they are enantiomers. If they are not mirror images but differ in spatial arrangement, they are diastereomers. If they have an identical spatial arrangement, they are the same compound.

Expert Solution
Step 1 Theory

In order to calculate whether a pair of molecule are Enantiomers or Diastereomers or same,

first determine the configuration of each asymmetric carbon atom of both the molecules.

Then compare their configuration 

If two molecules have opposite configuration at each asymmetric carbon atom, then they are Enantiomers.

If two molecules configuration are same at each carbon atom, they are same molecules.

For molecules to show Diastereomerism, firstly it should have more than 2 symmetric carbon centers. Then if two two molecules have same configuration of few carbon atoms and opposite for few other carbon atoms, then they are Diastereomers.
