Molten aluminium bromide is poor conductor of electricity. Explain.

Explanation

### Step-by-Step Solution:

1. **Understanding Aluminium Bromide (AlBr3)**:
- Aluminium bromide is an ionic compound composed of aluminium ions (Al³⁺) and bromide ions (Br⁻). In its solid state, it forms a crystalline lattice structure where these ions are held together by strong ionic bonds.

2. **Melting of Aluminium Bromide**:
- When aluminium bromide is heated, it melts and transitions from a solid to a molten state. During this process, the ionic bonds are broken, allowing the ions to move freely.
