### Molecular Stereochemistry Analysis

**Objective**: For each pair of molecules, determine if they are identical, enantiomers, diastereomers, constitutional isomers, or unrelated.

---

#### Pair 1:

- **Molecules**: Both structures feature a three-carbon backbone with an OH group attached.
- **Configuration**: 
  - The first molecule has the OH group in a wedge position, indicating it is coming out of the plane. 
  - The second molecule has the OH group in a dash position, indicating it is going into the plane.
  
**Conclusion**: These are enantiomers since they are mirror images but not superimposable.

---

#### Pair 2:

- **Molecules**: Cyclic structures with three cyclohexane carbons and one chiral center.
- **Configuration**: 
  - The first has OH and F both in the equatorial position.
  - The second has OH in the equatorial position and F in the axial position.
  
**Conclusion**: These are diastereomers as they are not mirror images and have different configurations at the chiral center.

---

#### Pair 3:

- **Molecules**: Both involve fluorine, bromine, and an OH group attached to a cyclohexane ring.
- **Configuration**: 
  - In the first, both F and Br are in a wedge orientation.
  - In the second, F is in a wedge and Br is in a dash orientation.
  
**Conclusion**: These are also diastereomers due to differing spatial arrangements and not being mirror images.

---

#### Pair 4:

- **Molecules**: Polycyclic structures with two OH groups.
- **Configuration**: 
  - The first molecule has both OH groups pointing upwards.
  - The second has one OH group pointing up and one down.
  
**Conclusion**: These are diastereomers, as they have non-mirror image relationships due to differing positions of the OH groups.

This analysis helps identify stereochemical relationships essential for understanding molecular interactions and properties in chemistry.
