Answer:

  • The correct option is B. The nonpolar substance has a lower boiling point than the polar substance.

Explanation:

  • Substances with hydrogen bonding, an intermolecular force, will have much higher  boiling points than those that have ordinary dipole-dipole intramolecular forces. Non-polar molecules have lower boiling points, because they are held together by the weak van der Waals forces.

Note

  • However, if size of non polar increases, then its boiling point increases due to increases in van der walls forces with large size.
