**Exercise: Identifying Isomers**

Determine whether each pair of formulas corresponds to enantiomers, diastereomers, structural isomers, or identical molecules.

**Pairs:**

(a)  
- Left: Molecule with a central carbon atom bonded to CH₃, Br, F, and H.
- Right: Same molecule but with a mirror image orientation (as depicted by dashed and wedged bonds).

(b)  
- Left: Molecule with CH₃, H, CO₂H, and CH₂OH attached to a central carbon.
- Right: Molecule with an identical formula but different structural arrangement around the carbon backbone.

(c)
- Left: Cyclopentane ring with Br and F substituents at 1,3 positions, both on wedge bonds.
- Right: Cyclopentane ring with Br and F substituents at 1,3 positions, inverted stereochemistry.

(d)
- Left: Molecule with a central carbon bonded to two Cl atoms and two CH₃ groups.
- Right: Same molecule but with CH₃ and OH substituents in different positions.

(e)
- Left: Three-carbon chain with OH and CO₂H groups in a specific arrangement.
- Right: Similar structural formula with a slightly different arrangement of OH and CO₂H groups.

(f)
- Left: Molecule with a central carbon bonded to OH, Cl, NH₂, and CH₃.
- Right: Identical bonding pattern but different 3D orientation.

(g)
- Left: Molecule with CH₃, CN, and OH around a central carbon.
- Right: Similar structure presented in a different spatial orientation.

(h)
- Left: Cyclohexane ring with CH₃ and CH₂OH substituents.
- Right: Cyclohexane ring with HO and CH₃ substituents in different positions.

(i)
- Left: Cyclopentane ring with OH and H substituents in specific positions.
- Right: Cyclopentane ring with similar substituents in different stereochemical arrangement.

(j)
- Left: Cyclohexane ring with two CH₃ substituents at 1,4 positions.
- Right: Cyclohexane ring with same substituents but different stereochemical positions.

**Explanation:**

For each pair:
- **Enantiomers
