Which of the following statements is/are false? a. Petroleum is a single chemical compound. b. Coke is used as a reducing agent in the extraction of metals. c. Coal tar, coal gas and coke are obtained by heating coal in the absence of air.

  1. Only a

  2. Only a and b

  3. Only b

  4. Only b and c

  5. Only c

Show answer
Correct Option: A
Explanation:

Which of the following statements is/are false? a. The various compounds present in coal tar are separated by the process of fractional distillation. b. The naphthalene balls used to repel moths and other insects is a product of coal tar. c. Coal gas is a mixture of methane, nitrogen and carbon monoxide as major components.

  1. Only a

  2. Only a and b

  3. Only b

  4. Only b and c

  5. Only c

Show answer
Correct Option: E
Explanation:

Statement 'c' is a false statement. Coal gas contains a variety of calorific gases including hydrogen, carbon monoxide, methane and volatile hydrocarbons together with small quantities of non-calorific gases such as carbon dioxide and nitrogen. Thus, it is the correct option.
