Out of o- and p-dibromobenzene which one has higher melting point and why?

Text Solution

Verified by Experts

p-dibromobenzene has higher melting point than its o-isomer due to symmetry. Due to symmetry, p- isomer fits in the crystal lattice better than the o-isomer. Hence, p-dibromobenzene has higher melting point.
