The incorrect statement about Glucose is:
Biomolecules · Class 12 · JEE Main Previous Year Question
The incorrect statement about Glucose is:
- a✓
Glucose is soluble in water because of having aldehyde functional group
- b
Glucose remains in multiple isomeric form in its aqueous solution
- c
Glucose is an aldohexose
- d
Glucose is one of the monomer unit in sucrose
Glucose is soluble in water because of having aldehyde functional group
Step 1: Solubility Factors — Glucose is highly soluble in water due to its multiple groups forming hydrogen bonds, not just its aldehyde group.
Step 2: Structural Facts — In aqueous solution, glucose exists in an equilibrium between its open-chain, -pyranose, and -pyranose forms (mutarotation).
Step 3: Summary — Sucrose is made of glucose and fructose. Glucose is an aldohexose. These statements are correct, while Statement (a) is incorrect.
Common Mistake: Attributing everything in organic chemistry to the main functional group (aldehyde) while ignoring the alcohol groups.
