Vedclass · Accepted Answer

$1,4-$dichlorobenzene > $1,2-$dichlorobenzene > $1,3-$dichlorobenzene

Vedclass · Answer

(B) The melting point of $1,4-$dichlorobenzene is higher than those of $1,2-$ and $1,3-$ isomers due to its symmetrical structure,which allows for better packing in the crystal lattice. Comparing the melting points: $1,4-$dichlorobenzene: $323 \ K$ $1,2-$dichlorobenzene: $256 \ K$ $1,3-$dichlorobenzene: $249 \ K$ Thus,the correct order is $1,4- > 1,2- > 1,3-$dichlorobenzene.

The correct order of melting point of dichlorobenzenes is
