Action of diazomethane on phenol liberates _________

Options

A. `H_(2)`
B. `O_(2)`
C. `CO_(2)`
D. `N_(2)`

Explanation

To solve the question regarding the action of diazomethane on phenol, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this case are phenol (C6H5OH) and diazomethane (CH2N2).

2. **Understand the Reaction**:
- Diazomethane is a reagent that can react with phenols. When it reacts, it typically forms an ether-like compound through a methylation process.

3. **Reaction Mechanism**:
- When diazomethane reacts with phenol, it leads to the formation of an anisole (methoxybenzene) and liberates nitrogen gas (N2) as a byproduct. The reaction can be represented as:
\[ C_6H_5OH + CH_2N_2 \rightarrow C_6H_5OCH_3 + N_2 \]

4. **Identify the Products**:
- The product formed is anisole (C6H5OCH3) and nitrogen gas (N2) is liberated.

5. **Conclusion**:
- Therefore, the action of diazomethane on phenol liberates nitrogen gas (N2).

### Final Answer:
The action of diazomethane on phenol liberates **N2**.
