Solution

The correct option is C $B r_{2}$
$B r_{2}$ is completely non-polar because of no electronegativity difference and only weak van der walls force is holding them together.

Q. In which molecule is van der Waals force most likely to be important in determining the melting point and the boiling point?

State True or False.

The boiling point is directly proportional to the van der Waals' forces between the atoms/molecules. More is the force of attraction, higher is the temperature required to overcome these binding force and higher will be the boiling point.
