How do you explain the presence of an aldehydic group in a glucose molecule?

Explanation

To explain the presence of an aldehydic group in a glucose molecule, we can follow these steps:

### Step 1: Understanding the Structure of Glucose
Glucose is a simple sugar (monosaccharide) that has a specific structure. It is an aldohexose, which means it contains an aldehyde group (-CHO) and has six carbon atoms. The molecular formula of glucose is C6H12O6.

### Step 2: Reaction with Hydroxylamine
When glucose reacts with hydroxylamine (NH2OH), it forms an oxime. The aldehyde group in glucose reacts with hydroxylamine to form a double bond between the carbon and nitrogen, resulting in the formation of an oxime. The reaction can be represented as follows:
