Q. In which of the following molecules the van der Waals forces is likely to be most important in determining the melting and boiling point?

Chemical Bonding and Molecular Structure

Solution:

$Br_2$ is non-polar molecules and hence its melting and boiling points depend only on Van der Waals forces while all other molecules are having dipole moments hence their melting and boiling points depends upon dipole-dipole interactions.
