MCQ
Isomers of hexane, based on their branching, can be divided into three distinct classes as shown in the figure. $Image$ The correct order of their boiling point is
  • A
    $I > II > III$
  • ✓
    $III > II > I$
  • C
    $II > III > I$
  • D
    $III > I > II$
✓

Answer

Correct option: B.
$III > II > I$
b
Greater the extent of branching, lesser is the boiling point of hydrocarbon.

Hence $III > II > I$
