  • Question 1
    1 / -0
    Hydrogen gas obtained form natural gas is used in ___________.
    Solution
    Natural gas which is obtained from petroleum produces hydrogen gas. Hydrogen gas is used as fertilizer in the fields.
  • Question 2
    1 / -0
    Which one of the following material is used for making shoe polish?
    Solution
    Paraffin wax is used for making shoe polish. Paraffin wax act as a covering that protects the shoe surface from water, scratches, and fungal growth. Hence option A is corrrect.
  • Question 3
    1 / -0
    Which one of the following is less polluting fuel?
    Solution
    Natural gas is less polluting fuel because it contains lower carbon ($$C$$) content than the rest. It produces the fewest emission products of all other. As it produces the fewest greenhouse gases than the rest hence, we can say that it is a less polluting fuel.
    Hence, option $$A$$ is correct.
  • Question 4
    1 / -0
    The main constituent of coal is:
    Solution
    The main constituent of coal is $$carbon$$,
  • Question 5
    1 / -0
    Heavier crude oils have too much of:
    Solution
    Because heavier crude oils have too much carbon and not enough hydrogen, the cracking processes generally involve removing carbon from or adding hydrogen to the molecules and using fluid catalytic cracking to convert the longer, more complex molecules in the oil to the shorter, simpler ones in the fuels.
  • Question 6
    1 / -0
    Hydrocarbons are obtained from Kerogens through____.
    Solution
    The process of formation of petroleum causes the organic matter to change, first into a waxy material known as kerogen, which is found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons via a process known as catagenesis.
  • Question 7
    1 / -0
    Boiling point of petrol is:
    Solution
    Petrol is obtained at the temperature of $$35 - 70^{\circ}$$ when petroleum is heated in a refinery.
  • Question 8
    1 / -0
    Which of the following is basic compound present in coal tar?
    Solution
    Quinoline is basic compound present in coal tar. Other basic compound present in coal tar is pyridine. 
    Benzene and toluene are neutral compounds. 
    Phenol is acidic compound.
  • Question 9
    1 / -0
    Anthracene present in coal tar is __________ in nature.
    Solution
    Anthracene present in coal tar is neutral in nature. Other neutral hydrocarbons include benzene, toluene, and naphthalene.
  • Question 10
    1 / -0
    Kerogen is a:
    Solution
    Kerogen is a waxy, insoluble organic substance that forms when organic shale is buried under several layers of sediment and is heated. If this kerogen is continually heated, it leads to the slow release of fossil fuels such as oil and natural gas, and also the non-fuel carbon compound graphite.

    Hence, the correct option is $$A$$
