Explain Kolbe’s reaction with example.

Explanation

**Step-by-Step Solution:**

**Step 1: Introduction to Kolbe’s Reaction**
Kolbe’s reaction is an electrochemical reaction that involves the decarboxylation of carboxylic acids or their salts to form alkenes or substituted aromatic compounds. In the context of phenols, it specifically refers to the reaction of phenol with carbon dioxide in the presence of a base to form salicylic acid.

**Step 2: Starting Materials**
The starting material for Kolbe’s reaction is phenol (C6H5OH). The reaction occurs in the presence of carbon dioxide (CO2) and a base, typically sodium hydroxide (NaOH).
