MCQ
Arrange the following compounds in increasing order of their boiling points.
  1.  
  1. $\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{Br}$
  2.  
  • A
    $\text{(b) < (a) < (c)}$
  • B
    $\text{(a) < (b) < (c)}$
  • ✓
    $\text{(c) < (a) < (b)}$
  • D
    $\text{(c) < (b) < (a)}$
✓

Answer

Correct option: C.
$\text{(c) < (a) < (b)}$
Boiling points of isomeric haloalkanes decrease with increase in branching as with increase in branching surface area decreases which leads to decrease in intermolecular forces.
