Chemistry Question on Biomolecules
which statement is not correct for glucose?
A
When heated with HI it gives n-Hexane
B
it is aldohexose
C
it reacts with Hydroxyl amine
D
it contain furanose structure
Answer
When heated with HI it gives n-Hexane
Explanation
Solution
The correct answer is option (A): When heated with HI it gives n-Hexane
When glucose reacts with HI it does not produce n-hexane. Glucose undergoes a dehydration reaction that leads to the formation of alkenes as products. The major product of this reaction is n-hexene. Hexene has a chemical formula of C6H12 and has a linear structure. The reaction involves the removal of water from glucose that forms n-hexene.
