Arrange the following compounds in increasing order of their boiling points
(i) 
(ii)
(iii) 
(i) (b) < (a) < (c)
(ii) (a) < (b) < (c)
(iii) (c) < (a) < (b)
(iv) (c) < (b) < (a)
Answers (1)
Option (iii) (c) < (a) < (b) is correct. Here the given alkanes are isomeric. Therefore isomeric alkane’s boiling point decreases with increase in branching. When the branching of an alkane increases, the surface area decreases. This causes a decrease in intermolecular force.
