Which among the following reagents gives oxidation with alkene?

Options

A. `KMnO_(4)//overset(Theta)OH//Delta`
B. `O_(3)`
C. `C_(6)H_(5)COOOH`
D. All of these

Explanation

To determine which reagents give oxidation with alkenes, we will analyze each reagent provided in the question step by step.

### Step 1: Identify the Reagents
Let's consider the common reagents that can oxidize alkenes. The reagents mentioned in the video include:
1. KMnO4 (Potassium permanganate)
2. O3 (Ozone)
3. Peracetic acid (C6H5-COOOH)

### Step 2: Analyze KMnO4
- **Reaction with Alkenes**: KMnO4 in a basic medium performs oxidative cleavage of alkenes.
- **Mechanism**: The double bond in the alkene is cleaved, resulting in the formation of carbonyl compounds such as ketones and aldehydes.
- **Conclusion**: KMnO4 indeed oxidizes alkenes.

### Step 3: Analyze Ozone (O3)
- **Reaction with Alkenes**: Ozone undergoes ozonolysis with alkenes.
- **Mechanism**: The double bond is cleaved, producing aldehydes and/or ketones.
- **Conclusion**: Ozone also oxidizes alkenes.

### Step 4: Analyze Peracetic Acid
- **Reaction with Alkenes**: Peracetic acid is known for epoxidation of alkenes.
- **Mechanism**: The alkene reacts with peracetic acid to form an epoxide, which is a cyclic ether. The formation of an epoxide involves the addition of oxygen across the double bond.
- **Conclusion**: This reaction also qualifies as oxidation since it involves the addition of oxygen.

### Step 5: Conclusion
Since all three reagents (KMnO4, O3, and Peracetic acid) are capable of oxidizing alkenes, the answer to the question is:
**All of these reagents give oxidation with alkenes.**

### Final Answer:
**D) All of these**
