What is the reason p-Dichlorobenzene has higher m.p. than those of o- and m-isomers?

Options

  1. Ap-Dichlorobenzene forms stronger hydrogen bonds than the other isomers.
  2. Bp-Dichlorobenzene has a more symmetrical molecular structure, resulting in stronger van der Waals forces and t
  3. CThe para isomer has a larger molecular mass, leading to higher melting point.
  4. DThe ortho and meta isomers have more polarizable chlorine atoms, reducing their melting points.

Correct answer

B. p-Dichlorobenzene has a more symmetrical molecular structure, resulting in stronger van der Waals forces and t

Step-by-step solution

Correct Option is : (B) p-Dichlorobenzene has a more symmetrical molecular structure, resulting in stronger van der Waals forces and thus, higher mp than those of o- and m- isomers
