  • question_answer
      Why the boiling points of isomeric halo alkanes decrease with increasing branching?

    Answer:

      As the branching increases molecule tends to acquire spherical shape i.e. its surface area decreases, correspondingly the magnitude of van der Waals force also decreases. So, boiling point also decreases.
