The compound formed on oxidation of ethyl benzene is

Options

A. acetophenone
B. benzoic acid
C. benzophenone
D. benzyl alcohol

Answer

To find the compound formed on the oxidation of ethylbenzene, we can follow these steps:

### Step 1: Understand the Structure of Ethylbenzene
Ethylbenzene is a hydrocarbon that consists of a benzene ring (C6H5) with an ethyl group (C2H5) attached to it. The molecular formula can be represented as C6H5-CH2-CH3.

### Step 2: Identify the Oxidizing Agent
The problem specifies the use of an oxidizing agent, KMnO4 (potassium permanganate). KMnO4 is a strong oxidizing agent that can oxidize various organic compounds.

### Step 3: Determine the Oxidation Process
When ethylbenzene is oxidized, the ethyl group (C2H5) can be converted into a carboxylic acid. The oxidation process typically involves the removal of hydrogen atoms and the addition of oxygen.

### Step 4: Identify the Product of Oxidation
The oxidation of the ethyl group in ethylbenzene leads to the formation of benzoic acid (C6H5COOH). The ethyl group is oxidized to a carboxylic acid, while the benzene ring remains intact.

### Conclusion
The compound formed on the oxidation of ethylbenzene is **benzoic acid (C6H5COOH)**.
