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

• A. I > II > III
• B. III > II > I
• C. II > III > I
• D. III > I > II

Answer 1

Answer: (B)

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