The most appropriate explanation for classifying glucose and fructose as structural isomers is that they possess

A. Different molecular formulas but the same structural arrangement
B. The same molecular formula but different functional groups
✓
C. The same molecular formula and the same functional groups
D. Different molecular formulas and different functional groups

📝 Explanation

Glucose and fructose both have the molecular formula C6H12O6. Glucose is an aldehyde sugar (aldose), while fructose is a ketone sugar (ketose). This difference in the carbonyl functional group makes them structural isomers, not identical molecules.

📖 Additional Information

  • Different molecular formulas but the same structural arrangement
  • The same molecular formula but different functional groups
  • The same molecular formula and the same functional groups
  • Different molecular formulas and different functional groups

Glucose and fructose both have the molecular formula C6H12O6. Glucose is an aldehyde sugar (aldose), while fructose is a ketone sugar (ketose). This difference in the carbonyl functional group makes them structural isomers, not identical molecules.
