Pure phenol is colourless but gets converted into pink after sometime by placing in the open air. Give chemical equation.

Explanation

To understand why pure phenol turns pink when exposed to air, we need to look at the chemical reaction that occurs during this process. Here’s a step-by-step breakdown of the solution:

### Step 1: Structure of Phenol
Phenol is an aromatic compound with the molecular formula C6H5OH. It consists of a benzene ring (C6H5) with a hydroxyl group (OH) attached to it.

### Step 2: Exposure to Air
When phenol is left in the open air, it is exposed to oxygen (O2) from the atmosphere. This exposure leads to the oxidation of phenol.
