It is said that glucose has a cyclic stucture , then what about the formation of n-hexane when glucose was reacted with HI which indicated that it had a straight chain

Open in App

Solution

This is because the HI is a strong reducing agent because of which every oxygen atom in the glucose molecule is removed, and the ring structure also has an Oxygen atom, which is also removed in the process and hence a straight chain is formed.
