**Educational Content on Stereochemistry**

**Topic: Stereochemical Relationships in Isomers**

The exercise presented involves identifying the stereochemical relationship between each pair of isomers. The possible relationships include same compound (meso), constitutional isomers, enantiomers, and diastereomers. 

**Pairs:**

a. Two 2D molecular structures featuring hydroxyl groups (OH) and methyl groups (CH₃) attached to a central carbon chain:

   - Left Structure: Shows a hydroxyl group on the left, a methyl group on top, and a hydrogen on the right.
   - Right Structure: Shows a symmetrical configuration with hydroxyl and methyl groups.

b. Two molecular structures both featuring bromine (Br) and chlorine (Cl) atoms:

   - Both structures have different spatial arrangements of Br and Cl.

c. Pair of cyclohexane structures with methyl groups (CH₃) attached:

   - Both cyclohexane rings bear a methyl substituent with differing orientations.

d. Fischer projections of carbohydrate-like structures featuring hydroxyl groups:

   - Highlight differences in the orientation of hydroxyl groups (OH).

e. Cyclohexane ring structures, one with a bromine substituent:

   - The cyclohexane rings have different stereochemical arrangements visible.

f. Linear isomeric structures:

   - Both compounds have different substituents' orientations on a double-bonded framework.

**Instructions:**
For each set, analyze the stereochemical relationship between the given molecules. Consider aspects such as symmetry, configuration, and chiral centers to determine the correct categorization into one of the specified groups: meso compounds, enantiomers, diastereomers, or constitutional isomers. 

This exercise aims to enhance the understanding of molecular symmetry and stereochemistry, crucial for more advanced studies in organic chemistry.
