Question

For isomeric dihalobenzenes, para isomers have greater melting point than ortho isomers, but lower boiling point than ortho isomers. Why?

Answer 1

Answer:

Generally, the melting pointof para isomer is quite higher thanthat of ortho or meta isomers. This is due to the fact that it has a symmetrical structure and therefore, its molecules can easily pack closely in the crystal lattice.
