LPG, a common domestic fuel, stands for:

  1. Liquid propane gas
  2. Light petroleum gas
  3. Liquified petroleum gas
  4. Liquified paraffin gas
Show answer and solution

Coal gas is obtained from coal by:

  1. Fractional distillation
  2. Vacuum distillation
  3. Destructive distillation
  4. Steam distillation
Show answer and solution

Correct answer: C. Destructive distillation

Heating coal strongly in the absence of air, called destructive distillation, releases coal gas.

Saturated hydrocarbons whose carbon atoms form a ring are called:

  1. Cycloalkanes
  2. Arenes
  3. Alkanes
  4. Cycloalkenes
Show answer and solution

Correct answer: A. Cycloalkanes

Single-bonded carbon atoms joined in a closed ring make a cycloalkane.
