Which of the following compounds is obtained on the reaction of phenol with diazomethane.

Options

A. A simple ether
B. An aromatic ether
C. An ester
D. A Hydroxy toluene

Answer

To determine which compound is obtained from the reaction of phenol with diazomethane, we can follow these steps:

### Step 1: Understand the Reactants
- **Phenol** (C6H5OH) is an aromatic compound with a hydroxyl (-OH) group attached to a benzene ring.
- **Diazomethane** (CH2N2) is a reagent that can react with alcohols and phenols.

### Step 2: Identify the Reaction
When phenol reacts with diazomethane, the diazomethane acts as a methylating agent. The reaction involves the transfer of a methyl group (CH3) from diazomethane to the oxygen atom of the phenolic -OH group.

### Step 3: Write the Reaction
The general reaction can be represented as:
\[ \text{C}_6\text{H}_5\text{OH} + \text{CH}_2\text{N}_2 \rightarrow \text{C}_6\text{H}_5\text{OCH}_3 + \text{N}_2 \uparrow \]

Here, the product formed is anisole (methoxybenzene), which is an aromatic ether.

### Step 4: Identify the Product
The product of the reaction is:
- **Anisole (C6H5OCH3)**, which is classified as an **aromatic ether** because it contains an ether functional group (R-O-R') where R is an aromatic group.

### Conclusion
The compound obtained from the reaction of phenol with diazomethane is **an aromatic ether**.

### Final Answer
The correct option is **an aromatic ether**.
