When the substances $\mathrm{CCl}_4, \mathrm{CH}_4$ and $\mathrm{CF}_4$ are arranged is order of increasing boiling point, what is the correct order?

• A

  $\mathrm{CCl}_4, \mathrm{CF}_4, \mathrm{CH}_4$
• Correct answer
  B

  $\mathrm{CH}_4, \mathrm{CF}_4, \mathrm{CCl}_4$
• C

  $\mathrm{CF}_4, \mathrm{CCl}_4, \mathrm{CH}_4$
• D

  $\mathrm{CF}_4, \mathrm{CH}_4, \mathrm{CCl}_4$

Hence, the correct answer is option: 'B'.
