Nitration mixture is used to genarate

Options

A. `NO_(2)^(-)`
B. `NO_(3)^(+)`
C. `NO_(2)^(+)`
D. `NO_(3)^(-)`

Answer

To answer the question about what the nitration mixture generates, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of the Nitration Mixture**:
The nitration mixture typically consists of concentrated nitric acid (HNO3) and concentrated sulfuric acid (H2SO4).

2. **Write the Reaction**:
When HNO3 and H2SO4 are mixed, a chemical reaction occurs. The reaction can be represented as:
\[ HNO3 + 2H2SO4 \rightarrow NO2^+ + 2HSO4^- + H3O^+ \]

3. **Identify the Key Product**:
From the reaction, we can see that one of the main products formed is the nitronium ion (NO2^+). This ion is crucial in electrophilic aromatic substitution reactions, particularly in the nitration of benzene.

4. **Conclusion**:
Therefore, the nitration mixture generates the nitronium ion (NO2^+), which is used as an electrophile in further reactions.

### Final Answer:
The nitration mixture is used to generate the nitronium ion (NO2^+).
