Explain why p-nitrophenol is more acidic than phenol ?

Explanation

To explain why p-nitrophenol is more acidic than phenol, we can break down the reasoning into several steps:

### Step 1: Understanding the Structures
- **Phenol** has the structure C6H5OH, where the hydroxyl (-OH) group is directly attached to a benzene ring.
- **p-Nitrophenol** has the structure C6H4(NO2)OH, where a nitro group (-NO2) is attached to the benzene ring at the para position relative to the hydroxyl group.

### Step 2: Identifying the Effects of the Nitro Group
- The nitro group is a strong electron-withdrawing group due to its -I (inductive) and -R (resonance) effects.
