What is meant by destructive distilllation ? What are the products of destructive distillation of coal ?

Explanation

### Step-by-Step Text Solution

**Step 1: Define Destructive Distillation**
Destructive distillation is a chemical process that involves the decomposition of organic material through heating at high temperatures in the absence of air. This process breaks down the material into various products without combustion.

**Step 2: Explain the Process of Destructive Distillation of Coal**
In the case of coal, destructive distillation involves heating coal at very high temperatures (around 1000°C) in an airtight container, which prevents the entry of air. This high-temperature environment causes the coal to break down into several different substances.
