Ethyl iodide on reaction with potassium nitrate majorly gives :

Options

A. Ethyl nitrite
B. Nitro ethane
C. Amine
D. Acid

Answer

To solve the question regarding the reaction of ethyl iodide with potassium nitrate, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants are ethyl iodide (C2H5I) and potassium nitrate (KNO2).

2. **Understand the Nature of Potassium Nitrate**:
- Potassium nitrate is an ionic compound that dissociates in solution to form K+ and NO2- ions. The NO2- ion can act as a nucleophile due to the presence of a negative charge.

3. **Recognize the Nucleophilic Attack**:
- In this reaction, the nucleophile (NO2-) will attack the electrophilic carbon in ethyl iodide. Ethyl iodide has a carbon atom that is partially positive due to the presence of the iodine atom, which is more electronegative.

4. **Mechanism of Reaction**:
- The nucleophilic attack occurs as follows:
- The NO2- ion attacks the carbon atom of ethyl iodide, leading to the displacement of the iodine atom.
- This results in the formation of ethyl nitrite (C2H5ONO).

5. **Final Product**:
- The major product of the reaction between ethyl iodide and potassium nitrate is ethyl nitrite (C2H5ONO).

### Summary of the Reaction:
- Ethyl iodide + Potassium nitrate → Ethyl nitrite + K+ + I-

### Final Answer:
The major product formed when ethyl iodide reacts with potassium nitrate is **ethyl nitrite (C2H5ONO)**.
