Structure of glucose

  1. Apr 21, 2016 #1
    Why does glucose on prolonged heating with HI give n-hexane?
    What mechanism/reaction type is this? All I knew till now was that alcohols would give halogen substituted products with hydrogen halides.

    It's a reduction with hydroiodic acid being oxidized to iodate. Btw the same reaction is used in the synthesis of methamphetamine in beeaking bad.

    Is it a common mechanism in introductory organic chemistry?
