Question

What happens when D-glucose reacts with the following?

 

1. HI
2. NH_2OH
3. Br_2 water
4. HNO_3
5. HCN

 

Hint:

D-glucose undergoes oxidation, reduction, and condensation reactions due to its functional groups.

Answer 1

Step 1: Reaction of D-Glucose with Different Reagents \begin{enumerate} HI: Reduction of glucose to hexane occurs. \[ C_6H_{12}O_6 + HI \rightarrow C_6H_{14} \] \NH\(_2\)OH: Formation of oxime. \[ C_6H_{12}O_6 + NH_2OH \rightarrow C_6H_{11}NOH + H_2O \]  Br\(_2\) water: Oxidation of aldehyde to carboxylic acid. \[ C_6H_{12}O_6 + Br_2 + H_2O \rightarrow C_6H_{12}O_7 + 2HBr \]  HNO\(_3\): Oxidation of aldehyde and primary alcohol to dicarboxylic acid. \[ C_6H_{12}O_6 + HNO_3 \rightarrow C_6H_{10}O_8 + H_2O \] HCN: Formation of cyanohydrin. \[ C_6H_{12}O_6 + HCN \rightarrow C_6H_{12}O_6CN \]
