Single Choice

Arrange the following in the decreasing order of their boiling points :

A(I) > (II) > (III) > (IV)
Correct Answer
B(IV) > (III) > (II) > (I)
C(I) > (II) > (IV) > (III)
D(III) > (IV) > (II) > (I)

Solution

The greater the number of C atoms and straight chain the higher is the boiling point . So, I is greater than II. More is the branching , less is the surface area , so lower is the boiling point. Therefore, III is greater than IV.
Hence,Option (A) is correct.
