**Question 27 of 28**

**What is the relationship between these two sugars?**

Two molecular diagrams are shown:

- **Left Diagram**: 
  - Structure: A sugar molecule with the following arrangement:
    - At the top, a carbon double-bonded to oxygen (C=O), and a single hydrogen (H).
    - Below, a vertical chain with two hydroxyl groups (OH) on the right and one hydroxyl group and a hydrogen at the bottom carbon connected to CH₂OH.
    
- **Right Diagram**: 
  - Structure: A sugar molecule with the following configuration:
    - At the top, a carbon with a double-bonded oxygen (CHO) and hydrogen.
    - Below, a vertical chain with two hydroxyl groups (OH) on the left, one hydroxyl group and a hydrogen at the bottom carbon connected to CH₂OH.

**Options:**

A) Identical structures  
B) Enantiomers  
C) Diastereomers  
D) Constitutional isomers

**Question 27 of 28**

Below is a comparison of two molecular structures. Analyze the two chemical diagrams to identify their isomeric relationship.

**Molecular Structures:**

1. *Left Structure:* 
   - An organic molecule featuring an aldehyde group (CHO) at the top.
   - The central carbon is bonded to a hydrogen (H), two hydroxyl groups (OH), and a CH2OH group.
    
2. *Right Structure:*
   - Similar structure with an aldehyde group (CHO) at the top.
   - The central carbon is bonded identically to a hydrogen (H), two hydroxyl groups (OH), and a CH2OH group.

**Options:**

A) Identical structures  
B) Enantiomers  
C) Diastereomers  
D) Constitutional isomers  
E) Non-isomeric  

**Explanation:**

To determine the correct relationship, consider the spatial orientation and connectivity:
- **Identical Structures:** The molecules are exactly the same in all aspects.
- **Enantiomers:** Non-superimposable mirror images.
- **Diastereomers:** Stereoisomers that are not mirror images.
- **Constitutional Isomers:** Same molecular formula, different connectivity.
- **Non-isomeric:** Not related as isomers.

Assess the two molecules to understand their relationship based on these definitions.
