Isomers of hexane, based on their branching, can be divided into three distinct classes as shown in the
figure.


The correct order of their boiling point is

  1. I > II > III
  2. III > II > I
  3. II > III > I
  4. III > I > II

Solution

III > II > I
More the branching in an alkane, lesser will be the surface area, lesser will be the boiling point.
