Which compound can produce chloropicrin with `Cl_2 + NaOH`

Options

A. Nitromethane
B. Nitrophenol
C. Nitroethane
D. Nitrostyrene

Answer

To determine which compound can produce chloropicrin when reacted with chlorine gas (Cl2) and sodium hydroxide (NaOH), we can follow these steps:

### Step 1: Identify the reaction
We need to know the chemical reaction that produces chloropicrin (CCl3NO2). Chloropicrin is also known as trichloronitromethane.

### Step 2: Write the reactants
The reactants given in the question are:
- Chlorine gas (Cl2)
- Sodium hydroxide (NaOH)

### Step 3: Determine the compound that reacts
The compound that can react with Cl2 and NaOH to produce chloropicrin is nitromethane (CH3NO2).

### Step 4: Write the balanced chemical equation
The balanced chemical equation for the reaction is:
\[ \text{CH}_3\text{NO}_2 + 3 \text{Cl}_2 + 3 \text{NaOH} \rightarrow \text{CCl}_3\text{NO}_2 + 3 \text{NaCl} + 3 \text{H}_2\text{O} \]

### Step 5: Identify the product
From the equation, we can see that the product formed is chloropicrin (CCl3NO2), along with sodium chloride (NaCl) and water (H2O).

### Conclusion
The compound that can produce chloropicrin when reacted with Cl2 and NaOH is **nitromethane (CH3NO2)**.

### Final Answer
The correct option is **A: Nitromethane**.
