When chloroform is treated with conc `HNO_(3)` it gives

Options

A. `CHCl_2 NO_2`
B. `"CCl"_3NO_2`
C. `CHCl_2NO_3`
D. None of these

Answer

To solve the question of what chloroform (CHCl₃) produces when treated with concentrated nitric acid (HNO₃), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactant is chloroform, which has the chemical formula CHCl₃.
- The other reactant is concentrated nitric acid, represented as HNO₃.

2. **Understand the Reaction**:
- Chloroform can undergo nitration when treated with concentrated nitric acid. This reaction typically leads to the formation of nitro compounds.

3. **Write the Reaction**:
- The reaction can be represented as:
\[ \text{CHCl}_3 + \text{HNO}_3 \rightarrow \text{CCl}_3\text{NO}_2 + \text{H}_2\text{O} \]
- In this reaction, chloroform reacts with nitric acid to produce trichloro nitromethane (CCl₃NO₂), also known as chloropicrin, along with water (H₂O).

4. **Identify the Product**:
- The main product formed is CCl₃NO₂ (chloropicrin), which is a nitro compound.

5. **Evaluate the Options**:
- The options provided were:
1. CHCl₂NO₂
2. CCl₃NO₂
3. CHCl₂ and NO₃
4. None of these
- From our reaction, we see that the correct product is CCl₃NO₂.

6. **Select the Correct Answer**:
- Therefore, the correct answer is option 2: CCl₃NO₂.

### Final Answer:
When chloroform is treated with concentrated HNO₃, it gives CCl₃NO₂ (chloropicrin) and water.
