The major product of the reaction of ethyl bromide with silver nitrite is:

Options

A. Nitroethane
B. Nitroethane and ethyl nitrite
C. Ethyl nitrite
D. Ethane

Answer

To solve the question regarding the major product of the reaction of ethyl bromide with silver nitrite, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are ethyl bromide (C2H5Br) and silver nitrite (AgNO2).

### Step 2: Understand the Nature of Silver Nitrite
Silver nitrite (AgNO2) is a covalent compound. It does not dissociate into ions in solution, which is crucial for understanding the mechanism of the reaction.

### Step 3: Mechanism of Reaction
Since AgNO2 does not dissociate, the nitrogen atom in the nitrite group (NO2) will act as a nucleophile. The lone pair of electrons on the nitrogen will attack the carbon atom in ethyl bromide that is bonded to the bromine atom.

### Step 4: Nucleophilic Substitution
In this nucleophilic substitution reaction, the bromine atom (Br) will be replaced by the nitro group (NO2). The reaction can be represented as follows:
\[ \text{C2H5Br} + \text{AgNO2} \rightarrow \text{C2H5NO2} + \text{AgBr} \]

### Step 5: Identify the Product
The product formed from this reaction is nitroethane (C2H5NO2).

### Conclusion
Thus, the major product of the reaction of ethyl bromide with silver nitrite is nitroethane.

### Final Answer
The major product is **nitroethane (C2H5NO2)**.
