Which of the following compound can not reacts with hydroxylamine ?

Options

A.
B.
C.
D.

Explanation

To determine which compound cannot react with hydroxylamine, we need to analyze the options provided and understand the reactivity of hydroxylamine.

### Step-by-Step Solution:

1. **Understanding Hydroxylamine**: Hydroxylamine (NH2OH) is a compound that can react with carbonyl groups (C=O) such as those found in aldehydes and ketones. The reaction typically results in the formation of oximes and the elimination of water.

2. **Identifying the Options**: Without the specific compounds listed in the options, we will assume they include various functional groups such as aldehydes, ketones, alcohols, and possibly sterically hindered compounds.

3. **Analyzing Each Option**:
- **Option 1**: If this is a simple aldehyde or ketone, it will react with hydroxylamine to form an oxime.
- **Option 2**: If this compound is a tertiary alcohol or a sterically hindered ketone, it may not react with hydroxylamine due to steric hindrance preventing the formation of the carbonyl group necessary for the reaction.
- **Option 3**: Similar to Option 1, if it is an aldehyde or ketone, it will react.
- **Option 4**: Again, if it is a simple aldehyde or ketone, it will react.

4. **Conclusion**: Based on the analysis, the compound that cannot react with hydroxylamine is likely the one that is sterically hindered or does not have a carbonyl group available for reaction.

5. **Final Answer**: The compound that cannot react with hydroxylamine is **Option 2** (assuming it is a tertiary alcohol or a sterically hindered ketone).
