Question
Classify each pair of compounds as enantiomers, diastereomers, structural isomers, or identical compounds
The image presents four structural formulas, labeled I, II, III, and IV. These structures represent different stereoisomers of a sugar molecule, each with the generic formula of an aldohexose. ### Structural Details: 1. **Structure I** - Top: CHO (aldehyde group) - Second position: Hydroxyl group (OH) on the left, Hydrogen (H) on the right - Third position: Hydroxyl group (OH) on the left, Hydrogen (H) on the right - Bottom: CH2OH (primary alcohol group) 2. **Structure II** - Top: CHO (aldehyde group) - Second position: Hydrogen (H) on the left, Hydroxyl group (OH) on the right - Third position: Hydroxyl group (OH) on the left, Hydrogen (H) on the right - Bottom: CH2OH (primary alcohol group) 3. **Structure III** - Top: CHO (aldehyde group) - Second position: Hydrogen (H) on the left, Hydroxyl group (OH) on the right - Third position: Hydrogen (H) on the left, Hydroxyl group (OH) on the right - Bottom: CH2OH (primary alcohol group) 4. **Structure IV** - Top: CHO (aldehyde group) - Second position: Hydroxyl group (OH) on the left, Hydrogen (H) on the right - Third position: Hydrogen (H) on the left, Hydroxyl group (OH) on the right - Bottom: CH2OH (primary alcohol group) ### Explanation: These structures represent different stereochemical configurations of the hydroxyl groups in the sugar molecule. The position of the hydroxyl groups relative to the main carbon chain influences the molecule’s properties and biological interactions, distinguishing each isomer's function and reactivity. Understanding these configurations is crucial in fields such as carbohydrate chemistry and molecular biology.
