Ethene on oxidation with `O_2` is presence of Ag give(s)

Options

A. epoxy ethane
B. ethlene oxide
C. oxiranes
D. None of the above

Answer

To solve the question regarding the oxidation of ethene (C₂H₄) with oxygen (O₂) in the presence of silver (Ag), we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are ethene (C₂H₄) and oxygen (O₂). Ethene is an alkene with the structure CH₂=CH₂.

2. **Understand the Reaction Conditions**:
- The reaction takes place in the presence of silver (Ag) and at a temperature of 200 degrees Celsius. Silver acts as a catalyst in this reaction.

3. **Write the Reaction**:
- The reaction can be represented as:
\[ \text{C}_2\text{H}_4 + \text{O}_2 \xrightarrow{\text{Ag}, 200^\circ C} \text{C}_2\text{H}_4\text{O} \]
- However, under these conditions, ethene undergoes a specific type of oxidation.

4. **Determine the Product**:
- The oxidation of ethene with oxygen in the presence of silver leads to the formation of a cyclic ether. The product formed is known as oxirane or epoxyethane (C₂H₄O).
- The structure of oxirane is a three-membered cyclic ether.

5. **Final Equation**:
- The overall reaction can be summarized as:
\[ \text{C}_2\text{H}_4 + \text{O}_2 \xrightarrow{\text{Ag}, 200^\circ C} \text{C}_2\text{H}_4\text{O} \quad (\text{oxirane}) \]

### Conclusion:
The oxidation of ethene (C₂H₄) with oxygen (O₂) in the presence of silver (Ag) at 200 degrees Celsius produces oxirane (C₂H₄O), also known as epoxyethane.
