In hydrolysis of aniline, the reagent used is

Options

A. Dil. HCl
B. Acetyl chloride
C. `CH_(3)OH`
D. None of these

Explanation

To determine the reagent used in the hydrolysis of aniline, we can follow these steps:

### Step 1: Understand Hydrolysis
Hydrolysis is a chemical reaction involving the breaking of a bond in a molecule using water. In the context of aniline, hydrolysis typically refers to the reaction of aniline with an acid to form anilinium ions.

### Step 2: Identify the Reagents
We are given four options:
1. Dilute HCl
2. Acetyl chloride
3. Methyl alcohol
4. None of these

### Step 3: Analyze Each Reagent
- **Dilute HCl**: This is a mineral acid that can protonate aniline, forming an anilinium ion. This is a common reagent used in the hydrolysis of amines.
- **Acetyl chloride**: This is typically used for acetylation reactions, not hydrolysis.
- **Methyl alcohol**: This is an alcohol and does not participate in the hydrolysis of aniline.
- **None of these**: This option suggests that none of the provided reagents are correct.

### Step 4: Conclusion
Based on the analysis, the reagent used in the hydrolysis of aniline is **Dilute HCl**.

### Final Answer
The correct answer is **Dilute HCl**.
