orthonylclorobenzene and paradiclorobenzene which one have more mealting point and boiling point?

Expert Answer:

The melting point and boiling point of para dichlorobenzene is higher than its ortho and meta isomers.
This is because para chlorobenzene has symmetrical structure and therefore molecules are closely packed in crystal lattice.
These molecules have strong intermolecular attraction.
Due to this, more energy is required to break the bonds.
