What happens when methane reacts with conc. `HNO_(3)` at high temperature?

Options

A. Nitromethane is formed
B. Methanol is formed.
C. `CO_(2) and H_(2)O` are formed.
D. CO and `H_(2)O` are formed.

Explanation

### Step-by-Step Solution:

1. **Identify the Reactants**: The reaction involves methane (CH₄) and concentrated nitric acid (HNO₃).

2. **Conditions of the Reaction**: The reaction takes place at high temperature, specifically around 400 degrees Celsius. This high temperature increases the rate of reaction by enhancing the frequency of collisions between reactant molecules.

3. **Write the Balanced Reaction**: When methane reacts with concentrated nitric acid at high temperature, the reaction can be represented as:
\[ \text{CH}_4 + \text{HNO}_3 \xrightarrow{\text{heat, } 400^\circ C} \text{CH}_3\text{NO}_2 + \text{H}_2\text{O} \]
Here, CH₃NO₂ is the product formed, which is known as nitromethane.

4. **Identify the Product**: The main product of this reaction is nitromethane (CH₃NO₂), along with water (H₂O).

5. **Applications of the Product**: Nitromethane has various applications, including its use as a fuel in racing cars and model aircraft, as well as in other specialized applications.

### Final Answer:
When methane reacts with concentrated HNO₃ at high temperature, nitromethane (CH₃NO₂) is formed.
