Question:
The correct statement with respect to D-glucose (x) and D-Fructose (y) is D-glucose (x) and D-fructose (y) are related as follows.
The correct statement with respect to D-glucose (x) and D-Fructose (y) is D-glucose (x) and D-fructose (y) are related as follows.
Show Hint
For sugar isomers, D-glucose and D-fructose are often compared based on their optical activity. D-glucose is dextrorotatory, and D-fructose is levorotatory.
Updated On: May 9, 2025
- Both x and y are dextrorotatory compounds
- Both x and y are levorotatory compounds
- x is levorotatory and y is dextrorotatory compound
- x is dextrorotatory and y is levorotatory compound
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
D-glucose is dextrorotatory, while D-fructose is levorotatory. This can be verified by analyzing their optical rotation. D-glucose rotates plane-polarized light to the right (clockwise), while D-fructose rotates it to the left (counterclockwise). Hence, the correct statement is that D-glucose is dextrorotatory and D-fructose is levorotatory.
