Conversion of p-Nitroacetanilide into p-dinitrobenzene

Explanation

To convert p-Nitroacetanilide into p-Dinitrobenzene, we will follow a series of chemical reactions. Here’s a step-by-step breakdown of the process:

### Step 1: Hydrolysis of p-Nitroacetanilide
- **Starting Material**: p-Nitroacetanilide (C8H8N2O3)
- **Reaction**: Treat p-Nitroacetanilide with concentrated sulfuric acid (H2SO4) followed by dilute sodium hydroxide (NaOH).
- **Mechanism**: The acetamide group (NHCOCH3) is hydrolyzed to form an amine group (NH2). The nitro group (NO2) remains unchanged.
- **Product**: p-Nitroaniline (C6H6N2O2)
