Question:
Which of the following compounds is obtained when glucose is heated with HI for a prolonged time?
Which of the following compounds is obtained when glucose is heated with HI for a prolonged time?
Show Hint
HI is a strong reducing agent that removes all oxygen atoms.
Updated On: Nov 12, 2026
- 6-iodohexanal
- n-Hexane
- 1-Hexene
- Hexanoic acid
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Prolonged heating with HI reduces glucose completely, removing every oxygen atom from the molecule.
Step 2: Reaction
\(\text{C}_{6}\text{H}_{12}\text{O}_{6} \xrightarrow{\text{HI}, \Delta} \text{n-C}_{6}\text{H}_{14}\)
Step 3: Meaning of the result
The formation of n-hexane shows that the six carbon atoms of glucose are in a straight unbranched chain.
Final Answer:
Prolonged heating of glucose with HI gives n-hexane. \[ \boxed{\text{(B) }\text{n-Hexane}} \]
