Which of the following statements regarding D-glucose is not correct?
A
Glucose gives a positive Tollen's test because of the presence of an aldehyde group in the openchain form.
B
Glucose undergoes mutarotation in aqueous solution due to interconversion of its 
- and 
forms.
- and forms. C
Glucose is an aldohexose containing six carbon atoms and an aldehyde group.
D
Glucose is a constituent monosaccharide unit of maltose and sucrose, but not of cellulose.
Text Solution
Verified by ExpertsThe correct answer is:
D
True - D-Glucose gives
Tollen's test due to its aldehyde in the open-chain form.
True -- It shows mutarotation via interconversion of 
- and 
-anomers in aqueous solution.
True - D-Glucose is an aldohexose (six carbons, an aldehyde group).
False - Cellulose is a polymer of 
-D-glucose units; glucose is a constituent of maltose (glucose + glucose) and sucrose (glucose + fructose) and cellulose.
