प्रश्न
Why is the boiling point of o-dichlorobenzene higher than p-dichlorobenzene, but the melting point of para-isomer is higher than ortho-isomer?
उत्तर
Because o-dichlorobenzene has a greater dipole moment and a greater dipole-dipole interaction than p-dichlorobenzene, it has a higher boiling point.
Boiling point
As opposed to ortho- and meta-isomer, p-dichlorobenzene has a higher melting point than that of o- and m-isomer due to its greater symmetry, which suits the crystal better.
