Question

Glucose when reduced with $HI$ and red Phosphours gives:

• A. n-hexane
• B. n-heptane
• C. n-pentane
• D. n-octane

Answer 1

The correct option is A n-hexane

On prolonged heating with red P & HI, it forms n-Hexane, ​suggesting that all the six carbon atoms are linked in a straight chain.​

This confirms the presence of 6 carbon chain in glucose. Hence option (a) is correct.
