    What happens when D-glucose is treated with the following reagents?
    () HI () Bromine water () HNO3
    () Bromine water () HNO3
    () Bromine water () HNO3
    () Bromine water () HNO3
    () Bromine water () HNO3
    () Bromine water () HNO3
    Ans : null () When D-glucose is heated with HI for a long time, n-hexane is formed.
