Answer : [tex]SO_{2}[/tex] is the molecule that exhibit dipole-dipole forces as its strongest intermolecular force.
Explanation : The shape or geometry of given molecules of [tex]N_{2}[/tex], [tex]H_{2}[/tex], [tex]CBr_{4}[/tex], [tex]BCl_{3}[/tex] and [tex]SO_{2}[/tex] are linear, linear, tetrahedral, trigonal planar and angular respectively.
The given molecules [tex]N_{2}[/tex], [tex]H_{2}[/tex], [tex]CBr_{4}[/tex], [tex]BCl_{3}[/tex] are symmetrical molecules. These symmetric molecules cannot exists as dipole even they contain polar bonds. Thus, these molecules will not exhibit dipole-dipole forces.
[tex]SO_{2}[/tex] molecule has polar bonds and unsymmetrical bonds as shown in attached image. This molecule cannot exhibit H-bonding. It exhibit only dipole-dipole forces.
Therefore, [tex]SO_{2}[/tex] molecule exhibit dipole-dipole forces as strongest intermolecular force.
