Reaction of alkene and paracid gives oxirane. This reaction is named as-

Options

A. Peroxidation
B. Oxidation
C. Prilezhaev Reaction
D. None

Answer

To solve the question regarding the reaction of alkene with peracid that produces an oxirane, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are alkenes and peracids. Peracids are organic compounds that contain a peracid functional group, usually represented as RCOOOH.

2. **Understand the Reaction**:
- When an alkene reacts with a peracid, it undergoes a reaction that leads to the formation of a cyclic ether known as an epoxide. This is a three-membered ring structure that includes one oxygen atom and two carbon atoms.

3. **Write the Reaction**:
- The general reaction can be represented as:
\[ \text{Alkene} + \text{Peracid} \rightarrow \text{Epoxide} + \text{Carboxylic Acid} \]
- For example, if we take ethylene (C2H4) and react it with peracetic acid (CH3C(O)OOH), we will form an epoxide (ethylene oxide) and acetic acid.

4. **Name the Reaction**:
- The specific name for the reaction between alkenes and peracids that produces an epoxide is called the **Prilezhaev Reaction**. This reaction is significant in organic chemistry for synthesizing epoxides from alkenes.

5. **Conclusion**:
- Therefore, the reaction of alkene with peracid that gives oxirane is known as the **Prilezhaev Reaction**.

### Final Answer:
The reaction of alkene and peracid gives oxirane, and this reaction is named the **Prilezhaev Reaction**.
