Arrange the following in the increasing order of properly indicated : o,m,p-dichlorobenzenes (Increasing order of melting points)
Because of its symmetry and structure, p-dichlorobenzene has the greatest melting point, followed by ortho, and finally meta. The melting point of a compound is related to its symmetry. As a result, the symmetry of the compound follows the same pattern as the melting point. The order is given below: m-Dichlorobenzene < o-Dichlorobenzen < p-Dichlorobenzene
