Question

P-dichloro benzene has higher melting point and lesser solubility than there of ortho and para isomer. Why?

Answer 1

p-Dichlorobenzene has higher melting point and solubility than those of o- and m-isomer. Discuss. The melting point of p-isomer is quite higher than ortho and meta isomers. This is due to the fact that it has symmetrical structure and therefore its molecules can be easily packed closely in crystal lattice.

Answer 2

Generally, the melting point of para isomer is quite higher than that of ortho or meta isomers. This is due to the fact that it has a symmetrical structure and therefore, its molecules can easily pack closes in the crystal lattice. ... Generally, para isomers are highly soluble in organic solvents than ortho.
