Question

WILL MARK BRAINIEST
If the molecules of two different substances have a similar size but the molecules of one substance are polar while the molecules of the other substance are nonpolar, what is most likely true about the substances?
A The polar substance has a lower boiling point than the nonpolar substance.
BThe nonpolar substance has a lower boiling point than the polar substance.
C Both substances have similar volatilities.
DBoth substances have similar solubilities.

Answer 1

The correct answer is letter B: the non polar substance has a lower boiling point than the polar substance.

Answer 2

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.
