The compound which reacts with hydroxylamine but does not react with Tollen's reagent is

Options

A. `CH_(3)CHO`
B. HCHO
C. `C_(2)H_(5)OH`
D. `CH_(3)COCH_(3)`

Explanation

To solve the question, "The compound which reacts with hydroxylamine but does not react with Tollen's reagent is," we will follow these steps:

### Step 1: Understand the Reactivity of Hydroxylamine
Hydroxylamine (NH2OH) is known to react with carbonyl compounds, which include aldehydes and ketones. This reaction forms oximes. Therefore, any compound that contains a carbonyl group (C=O) can potentially react with hydroxylamine.

### Step 2: Understand the Reactivity with Tollen's Reagent
Tollen's reagent is used to test for aldehydes. It contains silver ions (Ag+) that can be reduced to metallic silver (Ag) by aldehydes, which have a hydrogen atom attached to the carbonyl carbon (RCHO). Ketones, on the other hand, do not have this hydrogen atom and therefore do not react with Tollen's reagent.

### Step 3: Identify the Compounds
We need to identify a compound that reacts with hydroxylamine but does not react with Tollen's reagent. The options typically include:
- Aldehydes (which react with both)
- Ketones (which react with hydroxylamine but not with Tollen's reagent)
- Alcohols (which do not react with either)
- Other compounds

### Step 4: Analyze the Options
Given that we are looking for a compound that reacts with hydroxylamine but not with Tollen's reagent, we focus on ketones. For example, acetone (propanone) is a common ketone that fits this criterion.

### Step 5: Conclusion
The compound that reacts with hydroxylamine but does not react with Tollen's reagent is **acetone (propanone)**.

### Final Answer
**Acetone (propanone)** is the compound that reacts with hydroxylamine but does not react with Tollen's reagent.
