How are p-bromo aniline compounds obtained from aniline ?

Explanation

To obtain p-bromoaniline from aniline, we can follow these steps:

### Step 1: Acylation of Aniline
- **Reaction**: Aniline (C6H5NH2) is reacted with acetic anhydride (C4H6O3).
- **Product**: This reaction forms N-acetylaniline (C6H5NHCOCH3). The acylation introduces an acetyl group (COCH3) to the nitrogen atom of aniline, making it a less nucleophilic and a mild activating group.

### Step 2: Bromination of N-acetylaniline
- **Reaction**: The N-acetylaniline is then treated with bromine (Br2) in the presence of a solvent like carbon tetrachloride (CCl4) or another non-polar solvent.
