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

Options

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

Answer

To solve the question "Ethene on oxidation with O2 in the presence of Ag gives:", we will follow these steps:

### Step 1: Identify the Reactants
We start with ethene (C2H4), which is an alkene characterized by a carbon-carbon double bond.

### Step 2: Understand the Reaction Conditions
The reaction is carried out in the presence of oxygen (O2) and silver (Ag) as a catalyst, at a temperature of around 200 degrees Celsius.

### Step 3: Determine the Reaction Type
The oxidation of ethene involves the addition of oxygen across the double bond. In the presence of silver, this reaction leads to the formation of a cyclic ether.

### Step 4: Identify the Product
The product formed from the oxidation of ethene (C2H4) under the given conditions is ethylene oxide (C2H4O), which is also known as oxirane or epoxy ethene. This compound has a three-membered cyclic structure.

### Step 5: Conclusion
Thus, the final answer is that ethene on oxidation with O2 in the presence of Ag gives ethylene oxide (C2H4O).

### Summary of the Answer
Ethene (C2H4) + O2 (oxidation in presence of Ag) → Ethylene oxide (C2H4O)
