This is a short answer type question as classified in NCERT Exemplar
The melting point of p-dibromobenzene is greater because p-symmetry of bromobenzene allows it to fit better in a crystal lattice. As a result, breaking the bonds between the molecules requires a greater temperature, resulting in a higher melting point.
