Solution

The correct option is C p-Dichlorobenzene
p - Dichlorobenzene is more symmetrical than the o- and m- isomers. So, it fits more closely in the crystal lattice. Therefore more energy is required to break the crystal lattice of p - dichlorobenzene. Therefore p - dichlorobenzene has highest melting point than the 0- and m- isomers. It has melting point of 53.5 degree Celsius.
