Convert:
Aniline into 1, 3,5-tribromobenzene.

Explanation

To convert aniline into 1,3,5-tribromobenzene, we will follow a series of steps involving bromination and diazotization. Here’s the step-by-step solution:

### Step 1: Bromination of Aniline
- **Reaction**: Treat aniline (C6H5NH2) with bromine water (Br2 in H2O).
- **Mechanism**: The amino group (-NH2) is a strong activating group and directs the incoming bromine to the ortho and para positions of the benzene ring. Since we are using excess bromine, we will get bromination at both ortho and para positions.
- **Product**: The product of this reaction will be a mixture of ortho-brominated and para-brominated aniline, which can be represented as C6H4Br2 (with -NH2 at one position and -Br at ortho and para positions). The reaction also releases HBr.

### Step 2: Diazotization
