which pair shows the strongest and weakest intermolecular forces? a br (s), br (l) b br (l), br (s) c br…

Brief Explanations:

Intermolecular forces are strongest in solids as the molecules are closely - packed and have little freedom of movement. In gases, the molecules are far apart and have the weakest intermolecular forces. Bromine in solid state ($Br(s)$) has strong intermolecular forces and bromine in gaseous state ($Br(g)$) has weak intermolecular forces.

Answer:

C. $Br(s), Br(g)$
