MCQ
$B.P.$ of branched chain alkanes as compared to straight chain alkanes are
  • ✓
    Lower
  • B
    Equal
  • C
    Higher
  • D
    Independent of the chain
✓

Answer

Correct option: A.
Lower
a
(a)As the number of branches increases, surface area decreases, due to which Vander Waal forces of attraction decreases. Hence, boiling point also decreases.
