If one compares compound A,composed of nonpolar molecules,with compound B,composed of polar molecules,and both molecules have the same molecular formula,then it is true that:
A)both compounds have the same boiling point
B)A boils at a lower temperature than B
C)B will not boil
D)B boils at a lower temperature than A
E)we have to know the structural formula to determine the differences in boiling points of A and B

Quizplus · Accepted Answer

Polar molecules (compound B) have stronger intermolecular forces (like dipole-dipole interactions) compared to nonpolar molecules (compound A), which mainly rely on weaker London dispersion forces. This means compound B requires more energy (higher temperature) to overcome these forces and boil, making it boil at a higher temperature than compound A.
