Fructose on reduction gives a mixture of two alcohols which are related as:
Fructose on reduction gives a mixture of two alcohols which are related as:
Show Hint
• Epimers differ at only one chiral carbon
• All epimers are diastereomers
Updated On: Mar 19, 2026
- diastereomers
- epimers
- both (a) and (b)
- anomers
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Fructose is a ketohexose. On reduction, the carbonyl group (C=O) is reduced to an alcohol.
Step 2: Reduction of fructose gives two hexitols: sorbitol and mannitol.
Step 3: Sorbitol and mannitol differ in configuration at one chiral carbon (C-2). ⟹ They are epimers and hence diastereomers

Top Questions on Carbohydrates
- Given below are two statements:
Statement I: Sucrose is dextrorotatory. However, sucrose upon hydrolysis gives a solution having mixture of products. This solution shows laevorotation.
Statement II: Hydrolysis of sucrose gives glucose and fructose. Since the laevorotation of glucose is more than the dextrorotation of fructose, the resulting solution becomes laevorotatory.
In the light of the above statements, choose the correct answer from the options given below.- JEE Main - 2026
