4 PART QUESTION.
PART 1: The last unique stereoisomer is? PART 2: Which of these structures are enantiomers? PART 3: Which of these structures are diastereomers? PART 4:

Transcribed Image Text:**Consider these structures:**
The image presents three linear molecular structures, each with similar features but distinct orientations of hydroxyl (OH) groups. They are likely representations of stereoisomers of a sugar molecule, such as those seen in biochemistry.
**Structure Explanation:**
1. **First Structure (Leftmost):**
- Top: COOH (carboxyl group)
- Downwards:
- First carbon: H on the left, H on the right
- Second carbon: HO on the left, H on the right
- Third carbon: H on the left, H on the right
- Fourth carbon: HO on the left, H on the right
- Bottom: COOH (carboxyl group)
2. **Second Structure (Middle):**
- Top: COOH (carboxyl group)
- Downwards:
- First carbon: H on the left, H on the right
- Second carbon: HO on the left, H on the right
- Third carbon: H on the left, H on the right
- Fourth carbon: H on the left, OH on the right
- Bottom: COOH (carboxyl group)
3. **Third Structure (Rightmost):**
- Top: COOH (carboxyl group)
- Downwards:
- First carbon: H on the left, H on the right
- Second carbon: H on the left, OH on the right
- Third carbon: H on the left, H on the right
- Fourth carbon: HO on the left, H on the right
- Bottom: COOH (carboxyl group)
These diagrams represent different stereoisomers, explaining the three-dimensional arrangement of atoms in the molecules. This is crucial for understanding their biological functions and interactions.
