n- Butlbenzene on oxidation will give

Options

A. benzoic acid
B. butanoic acid
C. benzyl alcohol
D. benzaldehyde

Answer

To solve the question of what n-butylbenzene will yield upon oxidation, we can follow these steps:

### Step 1: Identify the structure of n-butylbenzene
n-Butylbenzene consists of a benzene ring with a butyl group (C4H9) attached to it. The structure can be represented as follows:

```
C4H9
|
C6H5 - C - C - C - C
```

### Step 2: Understand the oxidation process
When n-butylbenzene undergoes oxidation, we typically use a strong oxidizing agent such as potassium permanganate (KMnO4). This oxidizing agent will oxidize the alkyl side chain of the aromatic compound.

### Step 3: Determine the oxidation product
The oxidation of n-butylbenzene will primarily affect the butyl group. The key point to remember is that the oxidation will convert the terminal carbon of the butyl group into a carboxylic acid group (-COOH).

### Step 4: Identify the final product
The oxidation of n-butylbenzene will lead to the formation of benzoic acid (C6H5COOH). This is because the oxidizing agent will convert the terminal carbon of the butyl group into a carboxylic acid, while the benzene ring remains intact.

### Final Answer
Thus, the oxidation of n-butylbenzene will yield **benzoic acid**.
