Solution
Correct Answer:
Functional group isomers
- Molecular Formula: Both Glucose and Fructose share the same molecular formula, C6H12O6.
- Identify Structures:
- Glucose: An aldohexose (contains an aldehyde group −CHO at C-1).
- Fructose: A ketohexose (contains a keto group >C=O at C-2).
- Isomerism Type: Since they differ in the nature of their functional groups while having the same molecular formula, they are functional group isomers.
- Definitions of others:
- Epimers: Differ at only one chiral center other than the anomeric carbon (e.g., Glucose and Galactose).
- Anomers: Differ in configuration specifically at the anomeric carbon (C−1 for glucose).
This easy difficulty chemistry question is from the chapter biomolecules, covering the topic of monosaccharide isomerism. It appeared in the 2025 exam.
