Question

The molecules in compound AB are highly polar. The molecules in compound XY are nonpolar.

Which is true for these two compounds?


The forces between compounds AB and XY are the same.

Compound XY has a higher boiling point than compound AB.

Compound AB has a higher boiling point than compound XY.

Answer 1

The third answer, AB has a higher boiling point, is correct. The stronger the IMFs in a compound, the more energy required to overcome those forces to boil the compound. Thus, weaker compounds such as XY, which is nonpolar, will typically have lower boiling points.
