What happens when phenol is warmed with `CO_(2)` in the presence of aqueous NaOH?

Explanation

To understand what happens when phenol is warmed with CO₂ in the presence of aqueous NaOH, we can break down the process step by step:

### Step 1: Understanding the Reactants
Phenol (C₆H₅OH) is a compound consisting of a benzene ring with a hydroxyl (OH) group attached. When phenol is treated with carbon dioxide (CO₂) in the presence of sodium hydroxide (NaOH), a base, we can expect a reaction to occur.

**Hint:** Identify the functional groups in the reactants and their properties. Phenol is acidic due to the hydroxyl group, while NaOH is a strong base.

### Step 2: Formation of Phenoxide Ion
