Question

Which of the following compounds are toxic?
(A) Benzene.
(B) Toluene.
(C) Carbon tetrachloride.
(D) All of the above.

Answer 1

Hint : We know that some compounds present in crude oil like toluene, benzene, gasoline etc., are carcinogenic in nature, cause leukaemia and are highly toxic in nature. From the crude oil various petroleum products are derived which contaminate the environment.

Complete Step By Step Answer:
A hepatotoxic substance could be a substance that may be toxic or cause health effects. Benzene is found abundantly in nature. It is one of the main constituents of crude oil. It is found mainly as a component in gas emissions of volcanic eruption and forest fires. Benzene is a toxic gas, and exposure to it can cause leukaemia. Benzene is thought to cause cancer, supported proof from studies in both folks and work animals. Essentially it's a malignant neoplastic disease. Resolvent is irritating to the skin, eyes, and tract. It will cause general toxicity by body process or inhalation and is slowly absorbed through the skin. Carbon tetrachloride is one in all the foremost potent hepatotoxins (toxic to the liver), most in order that is widely employed in research projects to gauge hepatoprotective agents.
Exposure to high concentrations of carbon tetrachloride (including vapour) will have an effect on the central system, nervosum, degenerate the liver and kidneys and prolonged exposure could result in coma or death. Toluene is an irritator to the eyes. Inhaling in large quantities can be toxic to the eyes. It is a potential carcinogen agent. The chlorofluorocarbons were initially manufactured as a refrigerant as the refrigerants used till then were toxic to humans and accidents were common.
Therefore, the correct answer is option D.

Note :
Note that the n-Hexane causes peripheral neuropathy, which in severe cases leads to paralysis along with numbness of feet. The swallowing of gasoline and kerosene may cause irritation in the throat, difficulty in breathing and pneumonia. Some other effects may also affect the immune system, the blood, the organs, reproduction, and the developing foetus.
