Worked practice questions

Among para-, meta-, ortho-dichlorobenzene, the **melting point** is highest for:

  1. ortho-isomer
  2. meta-isomer
  3. para-isomer (symmetric, packs tightly in crystal lattice)
  4. All equal
Show answer and solution

Correct answer: C. para-isomer (symmetric, packs tightly in crystal lattice)

Para-dichlorobenzene has highest m.p. because its symmetrical linear structure packs efficiently in the crystal — stronger lattice energy. Ortho/meta have less efficient packing.
