Which of the following compounds is formed by the reaction of chloroform with Conc. `"HNO"_(3)`?

Options

A. `CHCl_(2)NO_(2)`
B. `"CCl"_(3)NO_(2)`
C. `CHCl_(3)HNO_(3)`
D. `CH_(2)ClNO_(2)`

Answer

To determine which compound is formed by the reaction of chloroform (CHCl3) with concentrated nitric acid (HNO3), we can follow these steps:

### Step 1: Identify the Reactants
We start with chloroform (CHCl3) and concentrated nitric acid (HNO3).

### Step 2: Understand the Reaction Mechanism
Chloroform contains three chlorine atoms and one hydrogen atom attached to carbon. When it reacts with concentrated nitric acid, the acidic hydrogen can be replaced by a nitro group (NO2) from the nitric acid.

### Step 3: Write the Reaction
The reaction can be represented as follows:
\[ \text{CHCl}_3 + \text{HNO}_3 \rightarrow \text{CCl}_3\text{NO}_2 + \text{H}_2\text{O} \]

### Step 4: Identify the Product
In this reaction, one hydrogen atom from chloroform is replaced by a nitro group, resulting in the formation of trichloronitromethane (CCl3NO2), commonly known as chloropicrin.

### Step 5: Conclusion
The compound formed by the reaction of chloroform with concentrated nitric acid is CCl3NO2.

### Final Answer
The correct compound formed is **CCl3NO2** (Chloropicrin).
