Solution :
The p- isomers being more symmetrical fits closely in the crystal lattice and thus has stronger inter-molecular forces of attraction than o- and m- isomers .
As during melting or dissolution , the crystal lattice breaks , therefore a large amount of energy is needed to melt or dissolve the p - isomer than the corresponding o-and m-isomers .
In other words , the melting point to the p- isomers is higher and its solubility lower than the corresponding o- and- m- isomers
