The residue left behind when destructive distillation of coal is carried out is coke.
Explanation:
- Destructive distillation of coal is a process in which coal is heated in the absence of air to produce various byproducts.
- The process involves heating coal to high temperatures, typically around 1,000 to 1,300 degrees Celsius.
- During this process, the volatile components of coal vaporize and are collected, leaving behind solid residue.
- The solid residue left behind after destructive distillation is called coke.
- Coke is a porous, carbon-rich substance that is used as a fuel and in industrial processes such as iron and steel production.
- It is produced by driving off volatile components such as water, coal gas, and coal tar, leaving behind a solid carbonaceous material.
- The coke produced from destructive distillation of coal has a high carbon content and is an important raw material in the production of steel and other metals.
- Therefore, the correct answer is B: coke.

Explanation:
Destructive Distillation of Coal:
- Destructive distillation of coal is a process where coal is heated in the absence of air to produce various by-products.
- This process typically involves heating coal in the absence of oxygen to break it down into different components.
Residue Left Behind:
- The residue left behind after the destructive distillation of coal is called coke.
- Coke is a porous, hard, black substance that remains after volatile components like coal gas, tar, and ammonia have been removed through the process.
Characteristics of Coke:
- Coke is a high-carbon product with few impurities, making it a valuable fuel source.
- It is used in industries like steel production, where it serves as a fuel and reducing agent in the blast furnace.
Uses of Coke:
- Coke is primarily used in the production of steel, where it provides the necessary heat and reducing properties to convert iron ore into iron.
- It is also used in industries like cement production, where it acts as a fuel and reduces the need for other energy sources.
Conclusion:
- In summary, the residue left behind after the destructive distillation of coal is coke, a valuable product with various industrial applications.
