Question

Which of the following is not generated by consumption of fossil fuel?
A.Sulfuric acid
B.Carbonic acid
C.Nitric acid
D.Nitrolic acid

Answer 1

Hint:Identify the formation and sources of these acids. Many oxides are emitted during burning of fossil fuels which later form dangerous acids resulting in degradation of the environment. One of these acids is an organic compound made from organic compounds.

Complete answer:
First let us understand about consumption of fossil fuels. Fossil fuels are obtained from natural processes like decomposition of dead and buried organisms and other natural waste. They are flammable geologic deposits of organic substances. These deposits converted into coal, natural gas and petroleum due to extreme heat and pressure inside the earth.
Fossil fuels are non-renewable sources of energy as once burned they cannot be renewed. Burning of fossil fuels generates a huge amount of carbon dioxide. Burning of fossil fuels also emits oxides of nitrogen and sulfur. These oxides and dioxides of nitrogen, sulfur and carbon later form acids which are carbonic acid, sulfuric acid and nitric acid. These acids then become the cause of acid rain which degrades soil and monuments on earth.
Nitrolic acid is an organic compound. It has a functional group $RC(N{O_2}) = NOH$ . It is not emitted by burning any fossil fuel. It is prepared by reaction of nitroalkanes with base and nitrite sources.

So, option D is the correct answer.

Note:
Carbon emitted by burning fossil fuels traps heat and leads to rising temperatures causing climate change. That is why current sources of fuel are not considered to be the future of energy and renewable sources like solar energy are being encouraged for energy needs. If we continue consuming fossil fuels at the current rate we will run out of fossil fuels in over $53$ years.
