Which is not a fossil fuel?
Which is not a fossil fuel?
The correct option is D Coal tar
Fossil fuels are natural resources that are formed after millions of years when dead and decayed organic matter gets buried under the earth by the action of earthquakes and volcanic eruptions.
The explanation for the correct option :
(A) Coke: It is obtained by heating bituminous coal at very high temperatures. It is not a fossil fuel.
(B) Lamp black: This is not a fossil fuel. Fossil fuels are formed from the remains of dead animals and plants that are buried under the ground for millions of years, while lamp black is formed by heating carbon-rich substances like turpentine oil or kerosene oil in a limited supply of air.
(D) Coal tar: It is obtained by cooling the gas that is formed during the destructive distillation of coal to approximately ambient temperature.
The explanation for the incorrect option :
(C) Charcoal: It is a fossil fuel and is also obtained from dead and decayed remains of plants and animals from the earth's crust after millions of years.
Thus, options (A), (B), and (D) i.e. Lamp black are the correct options.
