Out of the two compounds, p-dibromobenzene has the higher melting point. This is because the symmetry of p-dibromobenzene which makes the molecule fit better in crystal lattice. Due to this, it requires a higher temperature to break the bonds between the molecules and thus has a higher melting point.
