How will you convert the following (write the relevant equation):
Phenol to salicylic acid ?

Explanation

To convert phenol to salicylic acid, we will follow a series of chemical reactions. Salicylic acid is also known as ortho-hydroxybenzoic acid. The conversion involves a carboxylation reaction of phenol. Here’s a step-by-step breakdown of the process:

### Step 1: React Phenol with Sodium Hydroxide (NaOH)
Phenol (C6H5OH) is treated with sodium hydroxide (NaOH) to form sodium phenoxide (C6H5O⁻Na⁺).

**Equation:**
\[ \text{C}_6\text{H}_5\text{OH} + \text{NaOH} \rightarrow \text{C}_6\text{H}_5\text{O}^-\text{Na}^+ + \text{H}_2\text{O} \]
