Subjective Type

Amongst the isomeric dihalobenzenes which isomer has the highest melting point and why?

Solution

Amongst the isomeric dihalobenzenes para-isomer has the highest melting point. This due greater symmetry of para-isomer that first in crystal lattice better as compared to ortho and meta isomers.
