Explain why p-nitrophenol is more acidic than phenol ?

Explanation

To explain why p-nitrophenol is more acidic than phenol, we can follow these steps:

### Step 1: Understand the Structures
- **Phenol** is a simple aromatic compound with a hydroxyl (-OH) group attached to a benzene ring.
- **p-Nitrophenol** has a nitro (-NO2) group attached to the benzene ring at the para position relative to the hydroxyl group.

### Step 2: Identify the Role of the Nitro Group
- The nitro group is an electron-withdrawing group due to its strong electronegativity and resonance effects. This means it pulls electron density away from the rest of the molecule.
