How will you distinguish `1^(@)` and `2^(@)` hydroxyl groups present in glucose? Explain the reactions.

Explanation

To distinguish between the primary (1°) and secondary (2°) hydroxyl groups present in glucose, we can utilize the different reactivity of these hydroxyl groups towards oxidation. Here’s a step-by-step explanation of the process:

### Step 1: Understanding the Structure of Glucose
Glucose has the following structure:
- It contains an aldehyde group (-CHO) and five hydroxyl groups (-OH).
- The hydroxyl groups can be classified as:
- One primary hydroxyl group (at the end of the chain, -CH2OH).
- Four secondary hydroxyl groups (attached to the carbon atoms in the chain).
