On warming an aqueous solution of benzenediazonium chloride, the product obtained is

Options

A. Benzene sulphonic acid
B. Aniline
C. Pehnol
D. Amide

Explanation

To solve the question, "On warming an aqueous solution of benzenediazonium chloride, the product obtained is," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: Recognize that benzenediazonium chloride is represented as C6H5N2Cl. It consists of a benzene ring (C6H5) attached to a diazonium group (N2+) and a chloride ion (Cl-).

2. **Understand the Reaction Conditions**: The question specifies that the solution is warmed. Warming an aqueous solution of benzenediazonium chloride typically leads to a reaction where the diazonium group is unstable and can decompose.

3. **Recognize the Decomposition Reaction**: Upon heating, the diazonium group (N2+) in benzenediazonium chloride can lose nitrogen gas (N2) and result in the formation of phenol (C6H5OH). The reaction can be summarized as:
\[ C6H5N2Cl \xrightarrow{heat} C6H5OH + N2(g) + HCl \]

4. **Identify the Products**: The primary product formed is phenol (C6H5OH), and nitrogen gas (N2) is released as a byproduct.

5. **Conclusion**: Therefore, the product obtained on warming an aqueous solution of benzenediazonium chloride is phenol.

### Final Answer:
The product obtained is **phenol (C6H5OH)**.
