What happenes when `D-`glucose is treated with the following reagents?
(i). `HI`
(ii).Bromine water
(iii). `HNO_(3)`

Explanation

To determine the effects of various reagents on D-glucose, we will analyze each reaction step by step.

### Step 1: Reaction of D-Glucose with HI (Hydrogen Iodide)

When D-glucose is treated with HI, the reaction involves the reduction of the hydroxyl (OH) groups present in the glucose molecule. HI acts as a reducing agent, replacing the hydroxyl groups with hydrogen atoms.

**Product:** The product formed is n-hexane (C6H14), as all the OH groups are removed and replaced by H atoms.
