Question

In which of the following molecules the van der Waals forces is likely to be most important in determining the melting and boiling point? (A) CO (B) H2S (C) Br2 (D) HCl

Tardigrade Admin · Accepted Answer

Br2 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.

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?

$CO$

$H_{2} S$

$B r_{2}$

$H Cl$

$B r_{2}$ 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.
