The Total solution for NCERT class 6-12
p-Dichlorobenzenehas higher m.p. and lower solubility than those of┬аoтАУ and
m-isomers.Discuss.
p-Dichlorobenzeneis more symmetrical than┬аo-and┬аm-isomers. For thisreason, it fits more closely than┬аo-and┬аm-isomers inthe crystal lattice. Therefore, more energy is required to break the crystallattice of┬аp-dichlorobenzene. As a result,┬аp-dichlorobenzenehas a higher melting point and lower solubility than┬аo-and┬аm-isomers.
