How would you obtain
(i). Picric acid (2, 4, 6-trinitrophenol) from phenol,
(ii) 2-Methylpropene from 2-methylpropanol?

Explanation

To solve the given question, we will break it down into two parts:

### Part (i): Obtaining Picric Acid (2,4,6-trinitrophenol) from Phenol

1. **Start with Phenol**: The structure of phenol is a benzene ring with a hydroxyl group (-OH) attached to it.
\[ \text{C}_6\text{H}_5\text{OH} \]
