part a and b. fisher projection and zig zag 

**Title:** Understanding Stereoisomers through Fisher Projections and Zigzag Conformations

**Content:**

**Task:**
Convert the following Fisher projections into zigzag conformations and fill out the table describing the relationships between these stereoisomers. Label the table using:
- E for enantiomer
- D for diastereomer
- O for other
- M for meso
- C for constitutional isomers

**Fisher Projections:**

1. ![Molecule 1](CHO, H-OH, Br-H, H-OH, CH2OH)
2. ![Molecule 2](CHO, H-OH, H-Br, Br-H, CH2OH)
3. ![Molecule 3](CHO, HO-H, H-Br, H-OH, CH2OH)
4. ![Molecule 4](CHO, HO-H, Br-H, HO-H, CH2OH)
5. ![Molecule 5](CH2OH, H-OH, H-Br, Br-H, CHO)
6. ![Molecule 6](CH3, O=CO, Br-H, H-Br, CH2OH)

**Part A:**
**Relationship Table:**
- [Table showing relationships between molecules 1-6]

|   | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| 1 | X |   |   |   |   |   |
| 2 | D | X |   |   |   |   |
| 3 |   |   | X |   |   |   |

| 5 |   |   |   |   | X |   |
| 6 |   |   |   |   |   | X |

**Part B:**
If one of the above molecules (1-6) is considered meso or otherwise explain why in the space below:

Expert Solution
Step 1

Homomers : Two isomers having superimposable relationship with each other are called homomers.

Enantiomers : Two isomers having non-superimposable mirror image relationship are called enantiomers.

Diasteromers : Two isomers having non-superimposable no mirror image relationship are called diasteromers.

Meso : Compound having plane of symmetry is called meso form.

Constitutional isomers : Two compounds having same molecular formula but different in structure/stereochemistry are called constitutional isomers.
