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

Options

  1. AI > II > III
  2. BIII > II > I
  3. CII > III > I
  4. DIII > I > II

Correct answer

B. III > II > I

Step-by-step solution

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