Useful substances obtained from petroleum and natural gases are known as?
(A) Petroleum products
(B) Petrochemicals
(C) Chemicals
(D) None of these

Answer 1

Hint: Petroleum and natural gas are fossil fuels. They are made over the millions of years. Fossil fuels like natural gas and petroleum are formed inside the earth’s crust or between the rocks over a period of time from the remains of dead and decayed plants and animals.

Complete answer:
As we know that natural gas and petroleum are present inside the earth’s crust and takes millions of years to form, so their extraction is a precious process.
Natural gas is one of the cleanest and environmentally friendly fossil fuels.
So, the products of petroleum and natural gases are known as petrochemicals. These are the renewable sources.
In general terms the useful products obtained from petroleum are termed as petrochemicals, but in a more wide term it also includes other fossil fuels like natural gas and coal.
Therefore, Useful substances obtained from petroleum and natural gases are known as petrochemicals. These petrochemicals are of great importance in the day to day life and also in the big industries.
So, the correct option is B i.e. Petrochemicals.

Note:
Some of the examples of these petrochemicals are petroleum liquefied gas which is the common source of fuel in the household. Or the products made from the petrochemicals are the plastics, explosives, fertilizers, soaps, detergents, drugs. Petrochemicals also help in the manufacture of synthetic fibres. We also have our national Ministry of Petroleum and Natural gas that manages the extraction and the supply of petroleum, natural gas and other fossils like coal around the country.
