Question

Give two reasons to support the cyclic structure of glucose.

Answer 1

Ello user !!!!!!!!!!!

Here is your answer,

=============================================

It is important to note that the linear form of glucose makes up less than 0.02% of the glucose molecules in a water solution.

The rest is one of two cyclic forms of glucose that are formed when the hydroxyl group on carbon 5 (C5) bonds to the aldehyde carbon 1 (C1).

=============================================

HOPE THIS HELPS YOUU :)

AND STAY BLESSED.

Answer 2

Glucose crystalline structure.

Glucose pentaacetate.

Explanation:

• Glucose is the monomer of the different carbohydrates present in the living organisms.
• Glucose structure is linear and can be confirmed by the fact that hexane can be obtained from the glucose.
• Glucose can exist in cyclic structure as well. The glucose crystalline structure exist in the alpha and beta form at 303 K and 371 K. This reaction can not be given by linear structure of glucose.
• The glucose pentaacetate structure cannot be reacted with the hydroxylamine. The free aldehyde group is absent that cannot be explained by its linear structure.
