If a liquid compound decomposes at its noiling point, which method (s) an can you choose for its purification. It is known that the compound is stable at low pressure, steam volatile and insoluble in water.

Explanation

To purify a liquid compound that decomposes at its boiling point, is stable at low pressure, steam volatile, and insoluble in water, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Properties of the Compound**:
- The compound decomposes at its boiling point, indicating that traditional distillation methods would not be suitable as they would lead to decomposition during the process.
- It is steam volatile, meaning it can be carried over by steam.
- It is insoluble in water, which is important for the purification method.
