Which of the following compounds is obtained when glucose is heated with HI for a prolonged ?

Options

  1. A6-iodohexanal
  2. Bn-Hexane
  3. C1-Hexene
  4. DHexanoic acid

Correct answer

B. n-Hexane

Step-by-step solution

Glucose on prolonged heating with concentrated HI undergoes complete reduction to form n-hexane. This reaction indicates that all the six carbon atoms in glucose are linked in a straight unbranched chain. The reaction is given by: CHO-(CHOH)₄-CH₂OH HI, CH₃-CH₂-CH₂-CH₂-CH₂-CH₃ (n-hexane) Answer: n-Hexane
