An organic compound having molecular formula `C_(3)H_(6)O` does not react with 2,4-dintrophenol hydrazine and does not react Na metal. The compound is expected to be:

Options

A. `CH_(3)- CH_(2) -CHO`
B. `CH_(3) -CO -CH_(3)`
C. `CH_(2) =CH -CH_(2) -OH`
D. `CH_(2) =CH -OCH_(3)`

Explanation

To solve the question regarding the organic compound with the molecular formula \( C_3H_6O \) that does not react with 2,4-dinitrophenylhydrazine and does not react with sodium metal, we can follow these steps:

### Step 1: Analyze the Molecular Formula
The given molecular formula is \( C_3H_6O \). This indicates that the compound could potentially be an aldehyde, ketone, alcohol, or ether.

**Hint:** Look at the functional groups associated with the given molecular formula and their typical reactions.

### Step 2: Check for Aldehyde and Ketone Reactivity
Aldehydes and ketones typically react with 2,4-dinitrophenylhydrazine to form hydrazones. Since the compound does not react with this reagent, it cannot be an aldehyde or a ketone.

**Hint:** Recall that aldehydes and ketones have a carbonyl group (C=O) which is reactive towards 2,4-dinitrophenylhydrazine.

### Step 3: Evaluate the Alcohol Option
Next, we consider whether the compound could be an alcohol. Alcohols react with sodium metal to produce alkoxides and hydrogen gas. Since the compound does not react with sodium metal, it cannot be an alcohol.

**Hint:** Remember that alcohols contain a hydroxyl group (-OH) which is reactive with sodium.

### Step 4: Consider the Ether Option
The remaining option is that the compound is an ether. Ethers do not react with 2,4-dinitrophenylhydrazine or sodium metal, which aligns with the information given in the question.

**Hint:** Ethers are characterized by an R-O-R' structure and are generally unreactive towards the reagents mentioned.

### Conclusion
Since the compound does not react with either 2,4-dinitrophenylhydrazine or sodium metal, the expected compound is an ether. Therefore, the correct answer is:

**The compound is expected to be: Option D - \( CH_2CHOCH_3 \)**
